I will get back to this when I'm building my railroad. It is intriguing. Many years ago I was an over the road truck driver. I had a railroad in the top bunk. Rather then use a conventional power pack, I got a 2n3055 transistor, heat sink, A dpdt switch, and just used the trucks 12v power out of a cigarette lighter. Simple stupid effective. This looks like worth exploring. Thx
Big thank you Jimmy. Got my wifi board in the mail yesterday and after a trouble free 45 minutes, dcc++ was gone and I was running my first engine through my phone. Big smile on my dial! No more running from my laptop to stop an out of control train!
thanks to Dcc++ i was able to finally get my analog locos into DCC which was a real game changer for me. Also a big "THANK YOU" to you for bring this to the community! and thanks to Ron's train N thing for invite us to this amazing channel - Cheers from BA
The price point of entry is what drew me towards this system as I'm getting started with FreemoN. This was super easy to sit down and configure and I quickly had my first train running as a test using the web based controls. Can't wait to fine tune and expand this system as my system grows. Thanks for sharing... absolutely agreed that it's a game changer setup and the DCC++EX groups support and information is great!
I used the ESP-01 module when I built my setup a few months ago, and it has performed flawlessly. My layout is in the garage and it boots up and is ready to go in just a few seconds. I use Station mode; AP mode works fine, but I quickly tired of changing my phone's Wi-Fi network every time I wanted to run trains.

Excellent video. Thank you for doing this. I’ve used DCC++ EX on Arduino with my win10 laptop for a while. It connects with JMRI to run multiple locos, turnouts and sensors without problems. I got the WiFi card from England and paid more for shipping than the card itself. I have not tried to install the WiFi card yet and this video will help me.

Hi as a disable. person with a limited budget this is such a amazing solution. for my needs thank for time given in help so many kind regards Mike Cambridge U.K
Know the restrictions on being disabled on limited budget. I was fortunate enough at the beginning to have a little money to make purchases. Have trains, have track and an MRC throttle. Now all I have to do is get my sons to set up a train table. I've got a decent amount of stuff to get gping , just no current operating table. It takes time. 😎
Jimmy, You have out did yourself again with this video, it's great as usual. I have a dcc++ and have played around with DCC++ EX both of which I have found to be excellent. I have a Raspberry Pi 4B with JMRI connected to the DCC station and I login in with engine driver, or my wife's old I-Pad using the one for apple. I normally use Pi-sprog on the layout when I run DCC, or program my trains. My layout started 26 years ago as DC which I still use. I have double poll double throw switches . The layout was originally setup up for 4 DC throttles. All are either kits or ones I built from scratch, When I went to DCC, I changed the DC side to 2 throttles, this way I can setup the DCC to run on one switch and use the other to hookup to a programming track. It's a little complex but I have all the switches marked as to what they do. The only thing I found with DCC+ + or EX is I can not program trains with it. But that could just be me. My background was electronics and I did do some programming. My last gig was working on Cisco Routers and Switches for a major bank.
Ugh. This video came out 3 months after I spent 60 hours building a crude DCC system using a PIC16 microcontroller. But I was doing it as an exercise to learn more about microprocessors and assembly language. I didn’t even control locomotives; I just switched LED lights using the DCC protocol. I could’ve done the same thing using C and UART but then I wouldn’t learn as much about the microprocessor.
Working on my own DCC++EX - I have the mega and motor shield, power supply and power for the motor shield -- now need to get wi-fi shield. And DCC locos. DOH
Hi Jimmy DCC++ EX is Fantastic i have been using it and the different version and currently . While i am a Tech guy . I started using with Uno and Now with the latest version i am using a Mega and you Engine Driver and built one for my mates layout the only problem is Living in Australia It has been hard to get MakerFab WiFi SHield So i have been using Esp-01 it is very powerful and i love using My DCC++EX main on my mates track as i have mostly DC N Scale and only a couple of DCC Locomotives But i have modified my layout so 1 track is DC and the other is DCC . I want to say thanks i Use your design of the Station stop Arduino on my DC and i have IR sensors around the track to control the speed of my DC I am not good a programing but i can read and modify code.. I do enjoy your videos Thank you Regards Greg
Thanks for the video and information. I currently use a Raspberry Pi with a pi-sprog3 plus running JMRI but I am always interested in trying out new ways of controlling my railway :-) As I need to be able to program my decoders I will probably continue to use JMRI but will be interested to see how DCC++Ex develops. All I need to do now is see if I can find the various items needed over here in the UK :-) Thanks again and thanks for Bible verses.
I followed this video and was successful! I used the ESP-01 with a breadboard to share the 3.3v power and its definitely flaky but it works. I ordered the wifi shield to hopefully resolve that rather than using breadboard power supply. Thanks for making this video!!!
Thank-you for this video; this is a really interesting system. The major draw of the DCC++EX system for me is the ability to build it myself; I like building things, so this becomes another aspect of the hobby. The price is nice as well of course, and I suppose it also means I wouldn't be locked into proprietary components. I've seen and read a few other things about this (and DCC++) and people frequently refer to "limitations" of the system, but people don't talk much about those limitations. Do you suppose you could do a video on the (current) limitations of the system? For me, it's just as important to know what I *can't* do.
As one of the developers mentioned wifi is limited to 4-5 throttle connections connected directly to the command station....unless you use JMRI then you can have more....the other limitation is the memory and ram of the Arduino itself....you cannot use commercial DCC throttles with this system....that's a few and we are working on ways to solve that.
The DCC++EX installer is much easier to use than using the arduino editor. I also recommend the combined mega with wifi board, no jumpers needed unless you add a display.
Yes the automated installer is much easier, but after consulting with the DCC++EX guys. It’s still got some bugs to work out, which is why I did the IDE setup.
This is amazing. Setting up and wiring DCC and power are the two things I am most daunted by, honestly, but this looks like FUN! And the DCC++EX site has great instructions. And ... well, lower cost is always better. And I have a nice little laptop lying around that I can use as a support PC to load JRMI and do updates with. Awesome video and thank you Jimmy for bringing this to us!
I have a background in Robotics and process control... from 1987... I have no idea what he's talking about. Overwhelming!. I haven't touched electronics since that course, it was brutal and completely turned me off. Spent my teens fiddling with electronics, I have about 10 years experience, but this?!?
Jimmy, thanks for making these videos, they're very helpful. If you're still reviewing comments on this video, I have 2 questions. I'm trying to set up an Arduino Uno DCC++ command station, for use with a laptop for programming DCC, and a DCC-EX wireless command station with an Arduino Mega for use with modules. Q1: For the DCC++ programming setup, I believe the 9v power supply for the Arduino Uno is not required because the Uno is powered by the laptop via the USB port? I'm sure the guys at DCC-EX say don't use both? Q2: I've loaded the latest sketch to the Uno, connected a 13v 1.2a supply to the motor shield, connected the Uno to my laptop via the USB port and wires from the motor shield to my ops track only (A). But I have no lights on the motor shield. I tried a different Uno with the same results. I tested the power supply - it works ok. I tried a 3d Uno, an Elegoo Uno but, even though I have lights on the motor shield for the ops track, I also have a dim light on the negative connection (B) with no wires connected. And it still doesn't operate? I can't get JMRI to talk to it? But with the Elegoo unit, power is getting through to the track because the sound and lights of the loco are on? Any idea what the problem is? Do I have 2 failed Unos? Do I have a failed motor shield? Is there someway of testing the motor shield without the Uno? Sorry, that's more than 2 questions- lol.
I have just DC and like the hands on running of my trains. Not planning on getting any DCC trains but this was fun to see how you setup one for DCC++EX. 🚂🚂🚂💖💖💖 GOD BLESS 😊
I had a DCC++ (not EX) layout which used a second Arduino to provide the throttle controller - no PC needed (not even a Pi)! And it could program, too, in a clunky but functional fashion.
Great explanatory video, I'm in the process of setting up a DCC++EX setup. I managed to get the MakerFabs wifi shield through eBay. Once I've got things going I will see about sending some photos for your Virtual train show.
I brought a DCC loco off of EBay for £12 ~$15, its fitted with a Hornby R8249. When I first got the engine and opened it up and it was swimming in oil, but I powered it up on my dc track, and it ran?? But I noticed that there was smoke coming from one of the decoder components. I have cleaned it up and replaced the decoder but before fitting the new decoder I shorted out the pins to make it dc only and it will run around the track quite happily with the power supply set to 4-5volts, and its got quite a lot of power. I brought a elegoo mega and a cheap motor shield, cut the vin track and wired up a length of track to B+&- terminals and when I asked it to detect and the decoder, It gave me a choice of several, I choose R8249, and it made an entry in the roster, but I an unable to make the loco move using a throttle, I got error code 308. Thinking it may be due to the motor shield I brought a Deek-Robot motor shield but forgot to cut the vin before using it. Now I have a problem, have I fried the mega, the loco moves three four times as before but then gives me error 308, or do I have a problem with the loco, it rings out from the decoder pads back to the motor shield?
Hmmm. The deek robot shields are solid. It may have fried your board though. I would either cut or bend the VIN pin on the shield to make sure it doesn't happen again.
I used your recommended parts. Got it all together. Nice instructions on video. Loco wasn't working. I forgot to turn on track power. I am using for portable program and test track.
I'm looking to get this for my layout, as a second controller. I will be using it for my accessories and programming track. I will use my z21 Start for track power only. Looking forward to ordering mine :)
In my DCC++EX experience, if you connect Arduino Uno or Mega to computer using USB connection for JMRI you don't need to power Arduinos with external power supply. USB 5volt DC power seems to be enough. If the computer has Wi-Fi connection to home wireless router, JMRI WI-Throttle works very well with Android Engine Driver on a cell phone. Then both JMRI Operations track and Programming track outputs on the motor shield are available ... maybe these could be subject of another video.
While many people don't want or need the complexity of JMRI to just run trains, there are obviously a ton of serious railroaders who want all JMRI offers. We cover that on the we page. You don't need a WiFi board on the CS at that point, you use the WiFi in the computer running JMRI and connect to that. Be sure of your power requirements when running off USB power. It DOES work fine for probably most cases, but both the USB port on computers and the USB circuitry on the Arduino are limited to 500mA. If you had a Bluetooth or WiFi board on there or a lot of sensors and outputs connected directly to the Arduino, that might not work. The Mega can only take 800mA anyway, so the extra 300mA would only matter to someone with one of the situations I mentioned.
@@DCCEX All true ... but sooner or later model railroaders need to change CV values ... like when you buy a new engine preprogrammed with address 3. For myself, that's why I installed ... and learned the little I know about JMRI ... for DecoderPro. My experience so far is that DCC++EX works very well with DecoderPro and a programming track which for me is essential.
@@donaldkormos5529 I agree. And I like JMRI. But I do want to mention you can do all that without JMRI. You can program CV's right from a serial monitor in DCC++EX if you like, but some phone app throttles support CV programming as well. We are adding CV programming and turnout control to WebThrottle-EX, so tools like that can be used just as something to program locos even if you don't use them to control them. As much as I like JMRI and think it is extremely powerful, with power and options comes complexity. Plus, it is Java. it has a terrible user interface, is very convoluted, and has a steep learning curve. The page read feature is one of the nice benefits though! We've sped that up considerably. We do write code updates to JMRI as we come out with new features, so I'm not knocking it, just acknowledging we need an "I just want to run trains" (aka Conductor) solution.
I first heard of DCC++EX from Tom of Tom's Trains & Things. Got some of the parts right away but let them languish. Thanks for the excellent refresher. Hopefully, it's the extra push I need to get things going again.
I have a background in Robotics and process control... from 1986...! Hated the course as did my classmates. Most of the profs were stumbling around just trying to teach us. Sometimes we had to correct the profs! out of 87+/- students to start, 8 graduated. I have no idea what is going on in the video. It looks like I'm going to have to do some research, just to understand. Once I figure out what's what, just from the comments, This looks like my best bet. By the time I add on some sort of screen, keyboard, etc I'm guessing, from the prices I've seen, this will STILL be about 1/4 the cost of a "DCC starter system" and from what I understand, will be better then the "chief" top end systems. I have a lot to learn (and not a lot of time to learn it, as in, life span, lol!) but looks like it will be worth it!
The RP2040 isn't a mini computer, it's just a microcontroller like the Arduino boards use. It's made by the Raspberry Pi foundation and is quite capable.
This is a fantastic video and introduced me to something which I did not know even existed. For me the next step would be to introduce affordable decoders which could be fitted to N gauge locos from the 1990s and early 2000s. That would be an amazing game changer. Thanks so much for your efforts and for sharing.
You can install decoders, even sound decoders in N-Scale locos. In some cases, you have to do machining though. You have to take it to someone who can route out a space for a speaker. You can make decoders yourself too. Geoff Bunza has a board you can solder components to, but to makes something really small, you have to have surface mount components and that is usually not something the average Tinkerer can solder or bake. But Engineer level folks might tackle that. There are some non-sound decoders from China that are dirt cheap.
I'm about to start converting my DC system to DCC Ex following your video on this subject but I have a few questions. My N scale layout DC system with five main loops, a number of sidings and a turntable using a separate DC controller for each of the five main loops and isolating switches for sidings and turntable. My questions are going to DCC Ex do I just parallel up all loop feeders maintaining same polarity? The main layout is approximately 8X4 feet, each loop is probably about 20 feet. Also what size power supply would I need to probably run about 4 engines at any time? I would appreciate any advice in these areas. Really enjoy your Videos and advice. Thanks
Despite having a Z21, I'm going to have a go at this especially as I am pretty comfortable with coding. My only concern is track power. OK there are a few boards that can deliver hefty current, but I would prefer to fit boosters. Do you know if it is possible to piggy back or stack multiple motor drivers? What other options might there be. My basic research has only unearthed solutions that go way beyond my comfort zones.
I've been binge watching your videos for some time now and finally got my Arduino items to try DCC++/DCC++EX! I have one question, do you need a mega for the MakerFab WifiShield configuration or would a Uno R3 do? Thanks in advance and happy modelling!
Good evening I would like to know what replaces the Wifi card because on Amazon we can't find any more at the moment (Aruino Méga + schield motor and wifi). Thank you for your reply. Sincerely
@diydigitalrailroad, do you have a working link for the motorshield to use with the Mega? The link goes to a digital camera lol. Also is there a way to run more than 2 dc motors or is each setup restricted to just 2dc motors and thus requires multiple standalone units to control more?
What are the main advantages, other than the WiFi support, over DCC++ ? What are your thoughts on just getting the Arduino Mega with the ESP8266 built onboard? I understand that can work and would eliminate the extra shield or flying wires for an external ESP8266 chip.
I'm probably asking a question about DCC++EX Basestation that someone has answered and I apologize profusely. My memory is not what it has been lately. I want to run DCC++EX Basestation on my modular N scale layout. My layout is a combination of Ntrak with the 3 main lines, branch and the mountain line and a series of modules that are oNeTrak with mountain line *. Will I need to build a DCC++EX Basestation for each line or ?? I think when ready for shows I'll be operating a combined layout 36ft x 24ft or so. I need the correct websites addresses for DCC++EX main and any other super pertinent websites etc as I would like to add signals, transponding, more locomotives, consisting, and more. Thank you Rob
Hey Rob! No worries! DCC++EX is like any other DCC base station. You will only need one and then connect feeders to other modules. dcc-ex.com is going to be your best bet for info.
Need a little more help here, not being an electrician and new to these little circuit boards I'm trying to determine how you know if you cut enough of the VIN Connect to isolate the power from frying the Arduino? I have used an Hobby knife to cut between the contacts but not sure how to test it.
Hi, I using my train model to bring food to the table in my restaurant, but the guy that programs our software did failed and we have to many bugs to continue to use his software. we need to start from scratch and the solution you give in this video seems interested. Is it easy to link this DCC system to a custom app that will be able to select a specific train, send it to a specific table, stop 25 seconds and comeback to the station. It seems simple, but apparently is not. Do you know how much it should cost to program DCC++Ex to do such a thing?
Considering I was thinking about shelling out $$$$ for a Digitrax Zephyr on my small N scale setup; this is amazing Would you setup a discord or something so we can pester and ask questions? ive been wanting to get DCC but cost has been the killer
Good evening I would like to know if it is necessary to wire the Wangtongze Wifi shield before downloading the DCC++EX program. Thank you for your reply.
So what changes would you make to the hardware and wiring when doing this on an h.o. scale layout? Should i use a bigger power supply? What size is too big? Also with a dcc++ ex setup do i need to wire the arduino to a buss and then run feeder wires every 3 or 4 feet to the track like a normal dcc setup? Lastly what if i need more power for my dcc setup? Can a power booster be added to something like this? Most of my engines are old athern BB engines that either have already been converted or im converting to dcc sound which draw a little more current then most of the newer engines
A good 16 to 18vdc 4Amp+ laptop power supply works well with HO scale. Yes just to wires from DCC++EX terminal A {Main} to a normal DCC wiring Bus with drops every few feet would be preferred. Multiple power Motor Boards {boosters} are available like the IBT-2. for 5amp or more. Motor Board Boosters; dcc-ex.com/advanced-setup/supported-motorboards/index.html Visit us at DCC++EX Discord Server support discord.com/invite/PuPnNMp8Qf Regards, Kevin
Usually my eyes glaze over when talking about electronics. This was not so bad since it is the Lego approach of snapping blocks together. Thanks and rail on!
PS when uploading the file to the Arduino Mega there was two green leds one was flashing until the sketch was done uploading and now there is one led a steady red near the reset button
I have one question regarding your use of WiThrottle. Are you connecting to your Arduino Base Station directly through your home WiFi network, or to JMRI tethered to the base station via USB? I am asking because the project I have in mind is to build a coffee table layout and hoping to connect that railroad with as few electronic components as possible ( i.e. only one line of power to the coffee table) wirelessly. So far, I have only connected to a test loop with your base station set-up through home network and JMRI. I had to have an I.T. friend help me set a special open port to get through my lap top's firewall software which had us stumped for a while, LOL!
Thanks Jimmy. Awesome instructional vid! Did the guys at DCC++EX happen to mention anything about using this setup with more than 1 throttle/phone at the same time? Running two locos each with their own throttle.
This is awesome (I'm planning a Swiss N Layout). One question.......what about electrofrog turnout polarity? With a point motor, can DCC++ change the polarity? Lots still to learn! PS : Subscribed!
This ain't easy for a beginner. I'm hung up on a couple things. I have a main track. Is it a must that I have a programming track? Are power supplies and track all connected and powered up while I'm trying to load the programs? My wifi board from Robotshop somehow got a wrong zip code and was delivered to a wrong state. Can I set up without it using my laptop for control?
Thank you for this great video! This looks like its going to be somewhat challenging for most folks to undertake. I am excited about the possibilities. Would a raspberrypi zero W be able to provide the wifi? I guess you would just use jmri at that point anyway.
Good Morning, after putting this wifi card that you show in the video is it necessary to have some programming for it or not, just connect and connect the wires?
What would be cool would be to have the ability to attach potentiometers like MiniDCC to act as a normal throttle rather than having to use a mobile phone app.
I've been waiting for this to come out for years, I bet it's been out for a while already 🤣. I think your censoring of your WiFi SSID went away for a sec, too. Just letting you know.
The DCC++EX command station was very appealing to me just starting out in model railroading. I am a goober at electronics, but your video instructions are excellent. Thanks. I followed your instructions and those of the DCC++EX website using an Arduino Mega R3, Arduino motor shield, and Makerfab wifi shield. However when testing the locomotive using the JMRI and DCC++EX web throttles, all that I get is the engine startup and idle. Lights, bells, horn, movement, etc do not work. Not sure what I did wrong. My voltmeter says that the power to the mainline track is only about 12mV. I thought that my motor shield was bad, so I got another one. Same result. Seems that there is not enough power getting to the tracks. Any suggestions. Goober
I'm completely new to DCC, but not to electronics/ programming. I think DCC uses Pulse width Modulation to supply power to the track, so you can't accurately measure the track voltage with a voltmeter. I'm sure others will chip in if I am wrong about this. Good luck.
I will get back to this when I'm building my railroad. It is intriguing.
Many years ago I was an over the road truck driver. I had a railroad in the top bunk. Rather then use a conventional power pack, I got a 2n3055 transistor, heat sink, A dpdt switch, and just used the trucks 12v power out of a cigarette lighter. Simple stupid effective.
This looks like worth exploring. Thx

On your ESP-01 module, where does the ground wire connect to? Thanks

Thanks for pulling all of the parts into one source!
good vid jimmy keep posting vids up
The DCC++EX installer is much easier to use than using the arduino editor. I also recommend the combined mega with wifi board, no jumpers needed unless you add a display.
Yes the automated installer is much easier, but after consulting with the DCC++EX guys. It’s still got some bugs to work out, which is why I did the IDE setup.
This is blowing my mind! This is amazing. Thank you so much for making me aware of this.
This is amazing. Setting up and wiring DCC and power are the two things I am most daunted by, honestly, but this looks like FUN! And the DCC++EX site has great instructions. And ... well, lower cost is always better. And I have a nice little laptop lying around that I can use as a support PC to load JRMI and do updates with. Awesome video and thank you Jimmy for bringing this to us!
I have a background in Robotics and process control... from 1987... I have no idea what he's talking about. Overwhelming!. I haven't touched electronics since that course, it was brutal and completely turned me off. Spent my teens fiddling with electronics, I have about 10 years experience, but this?!?
Looks like the motor shield I got is DOA (no lights or anything) . Will have another one here in a day or two hopefully.
Thank you for posting this! I have been dealing with DCC++ for a while and am similarly impressed with this project.
Jimmy, thanks for making these videos, they're very helpful. If you're still reviewing comments on this video, I have 2 questions.
I'm trying to set up an Arduino Uno DCC++ command station, for use with a laptop for programming DCC, and a DCC-EX wireless command station with an Arduino Mega for use with modules.
Q1: For the DCC++ programming setup, I believe the 9v power supply for the Arduino Uno is not required because the Uno is powered by the laptop via the USB port? I'm sure the guys at DCC-EX say don't use both?
Q2: I've loaded the latest sketch to the Uno, connected a 13v 1.2a supply to the motor shield, connected the Uno to my laptop via the USB port and wires from the motor shield to my ops track only (A). But I have no lights on the motor shield. I tried a different Uno with the same results. I tested the power supply - it works ok. I tried a 3d Uno, an Elegoo Uno but, even though I have lights on the motor shield for the ops track, I also have a dim light on the negative connection (B) with no wires connected. And it still doesn't operate? I can't get JMRI to talk to it? But with the Elegoo unit, power is getting through to the track because the sound and lights of the loco are on?
Any idea what the problem is? Do I have 2 failed Unos? Do I have a failed motor shield? Is there someway of testing the motor shield without the Uno?
Sorry, that's more than 2 questions- lol.
Thank you for this video! It is the perfect solution to run the layout that I am currently building in a coffee table.
Having both Digitrax, and NCeDCC, I’m getting interested in this DCC System. Thanks for posting. always trying to keep my mind active.
I have just DC and like the hands on running of my trains. Not planning on getting any DCC trains but this was fun to see how you setup one for DCC++EX. 🚂🚂🚂💖💖💖
GOD BLESS 😊
I had a DCC++ (not EX) layout which used a second Arduino to provide the throttle controller - no PC needed (not even a Pi)! And it could program, too, in a clunky but functional fashion.
Awesome! Great guide. I've had a small problem with the decoder I used (Digitrax DH126) but there's a lot of help in the forums / Facebook groups etc.
Very intriguing. In the fast lane for us yet. Where only sketching out our new 5th line for DCC. Leaving the other 4 DC. Thanks for posting🚂🇨🇦
Looks pretty straightforward, if I only understood even a part of that LOL. Maybe one day.... I admire your easy step by step approach.
Great explanatory video, I'm in the process of setting up a DCC++EX setup. I managed to get the MakerFabs wifi shield through eBay. Once I've got things going I will see about sending some photos for your Virtual train show.
Ok im going to order one right now! Thanks
I brought a DCC loco off of EBay for £12 ~$15, its fitted with a Hornby R8249. When I first got the engine and opened it up and it was swimming in oil, but I powered it up on my dc track, and it ran?? But I noticed that there was smoke coming from one of the decoder components. I have cleaned it up and replaced the decoder but before fitting the new decoder I shorted out the pins to make it dc only and it will run around the track quite happily with the power supply set to 4-5volts, and its got quite a lot of power.
I brought a elegoo mega and a cheap motor shield, cut the vin track and wired up a length of track to B+&- terminals and when I asked it to detect and the decoder, It gave me a choice of several, I choose R8249, and it made an entry in the roster, but I an unable to make the loco move using a throttle, I got error code 308.
Thinking it may be due to the motor shield I brought a Deek-Robot motor shield but forgot to cut the vin before using it.
Now I have a problem, have I fried the mega, the loco moves three four times as before but then gives me error 308, or do I have a problem with the loco, it rings out from the decoder pads back to the motor shield?
Hmmm. The deek robot shields are solid. It may have fried your board though. I would either cut or bend the VIN pin on the shield to make sure it doesn't happen again.
Great video! I'm officially motivated now.
Just found your channel. As a person that loves trains and coffee I really enjoy your content. Keep up the good work!
This tutorial is very helpful for me. Thanks Jimmy
I used your recommended parts. Got it all together. Nice instructions on video. Loco wasn't working. I forgot to turn on track power. I am using for portable program and test track.
This is a great project!
I'm looking to get this for my layout, as a second controller. I will be using it for my accessories and programming track. I will use my z21 Start for track power only. Looking forward to ordering mine :)
In my DCC++EX experience, if you connect Arduino Uno or Mega to computer using USB connection for JMRI you don't need to power Arduinos with external power supply. USB 5volt DC power seems to be enough. If the computer has Wi-Fi connection to home wireless router, JMRI WI-Throttle works very well with Android Engine Driver on a cell phone. Then both JMRI Operations track and Programming track outputs on the motor shield are available ... maybe these could be subject of another video.
Throttle options will be a subject of another video.
While many people don't want or need the complexity of JMRI to just run trains, there are obviously a ton of serious railroaders who want all JMRI offers. We cover that on the we page. You don't need a WiFi board on the CS at that point, you use the WiFi in the computer running JMRI and connect to that.
Be sure of your power requirements when running off USB power. It DOES work fine for probably most cases, but both the USB port on computers and the USB circuitry on the Arduino are limited to 500mA. If you had a Bluetooth or WiFi board on there or a lot of sensors and outputs connected directly to the Arduino, that might not work. The Mega can only take 800mA anyway, so the extra 300mA would only matter to someone with one of the situations I mentioned.
@@DCCEX All true ... but sooner or later model railroaders need to change CV values ... like when you buy a new engine preprogrammed with address 3. For myself, that's why I installed ... and learned the little I know about JMRI ... for DecoderPro. My experience so far is that DCC++EX works very well with DecoderPro and a programming track which for me is essential.
@@donaldkormos5529 I agree. And I like JMRI. But I do want to mention you can do all that without JMRI. You can program CV's right from a serial monitor in DCC++EX if you like, but some phone app throttles support CV programming as well.
We are adding CV programming and turnout control to WebThrottle-EX, so tools like that can be used just as something to program locos even if you don't use them to control them.
As much as I like JMRI and think it is extremely powerful, with power and options comes complexity. Plus, it is Java. it has a terrible user interface, is very convoluted, and has a steep learning curve. The page read feature is one of the nice benefits though! We've sped that up considerably. We do write code updates to JMRI as we come out with new features, so I'm not knocking it, just acknowledging we need an "I just want to run trains" (aka Conductor) solution.
Thanks for the video and such a good explanation.
Would love to see you revisit all this with the latest DCC++ release and JMRI.
I first heard of DCC++EX from Tom of Tom's Trains & Things. Got some of the parts right away but let them languish. Thanks for the excellent refresher. Hopefully, it's the extra push I need to get things going again.
Lots of help to get you going, just ask! :)
I have a background in Robotics and process control... from 1986...! Hated the course as did my classmates. Most of the profs were stumbling around just trying to teach us. Sometimes we had to correct the profs! out of 87+/- students to start, 8 graduated. I have no idea what is going on in the video. It looks like I'm going to have to do some research, just to understand. Once I figure out what's what, just from the comments, This looks like my best bet. By the time I add on some sort of screen, keyboard, etc I'm guessing, from the prices I've seen, this will STILL be about 1/4 the cost of a "DCC starter system" and from what I understand, will be better then the "chief" top end systems. I have a lot to learn (and not a lot of time to learn it, as in, life span, lol!) but looks like it will be worth it!
The RP2040 isn't a mini computer, it's just a microcontroller like the Arduino boards use. It's made by the Raspberry Pi foundation and is quite capable.
This is a fantastic video and introduced me to something which I did not know even existed. For me the next step would be to introduce affordable decoders which could be fitted to N gauge locos from the 1990s and early 2000s. That would be an amazing game changer. Thanks so much for your efforts and for sharing.
You can install decoders, even sound decoders in N-Scale locos. In some cases, you have to do machining though. You have to take it to someone who can route out a space for a speaker. You can make decoders yourself too. Geoff Bunza has a board you can solder components to, but to makes something really small, you have to have surface mount components and that is usually not something the average Tinkerer can solder or bake. But Engineer level folks might tackle that.
There are some non-sound decoders from China that are dirt cheap.
Good video! There are also Arduino Megas for sale with a built in wifi module that may be a bit easier to set up
I'm about to start converting my DC system to DCC Ex following your video on this subject but I have a few questions. My N scale layout DC system with five main loops, a number of sidings and a turntable using a separate DC controller for each of the five main loops and isolating switches for sidings and turntable. My questions are going to DCC Ex do I just parallel up all loop feeders maintaining same polarity? The main layout is approximately 8X4 feet, each loop is probably about 20 feet. Also what size power supply would I need to probably run about 4 engines at any time? I would appreciate any advice in these areas. Really enjoy your Videos and advice. Thanks
The arduino can run on 12v too, just use security camera power splitter
One day I am going to do this, just for fun.
Despite having a Z21, I'm going to have a go at this especially as I am pretty comfortable with coding. My only concern is track power. OK there are a few boards that can deliver hefty current, but I would prefer to fit boosters. Do you know if it is possible to piggy back or stack multiple motor drivers? What other options might there be. My basic research has only unearthed solutions that go way beyond my comfort zones.
I've been binge watching your videos for some time now and finally got my Arduino items to try DCC++/DCC++EX! I have one question, do you need a mega for the MakerFab WifiShield configuration or would a Uno R3 do?
Thanks in advance and happy modelling!
Hello! You do need an arduino mega for the Wi-Fi setup
I used a MEGA with builtin esp8266 wifi, took a little effort to setup but works great.
Given none of the shields in this video are available any more, might be time for a refresh video on updated kit =)
thank you share great ideal video
from Australia
I see you have Kato double track. Can you please make a video on how to wire dog bone with turnouts with DCC++ Ex and reversing loops at ends?
Fantastic video thanks for placed on TH-cam and good explain !! 🙏🚂🚆😎.
HC Treintje Herman from Belgium 😁😀🚂🚆😎.
I run 12v to the computer and cut the vin trace on the motor shield and run it on 15v.
Good evening
I would like to know what replaces the Wifi card because on Amazon we can't find any more at the moment (Aruino Méga + schield motor and wifi).
Thank you for your reply. Sincerely
great video. i just want to know why at 6:30 you plug in power to the Arduino? i thought the usb cable would supply that
Hello Jimmy, this us just what I need for a test setup. I now need to find a good decoder which I can build in to one of my model trains in n scale.
@diydigitalrailroad, do you have a working link for the motorshield to use with the Mega? The link goes to a digital camera lol. Also is there a way to run more than 2 dc motors or is each setup restricted to just 2dc motors and thus requires multiple standalone units to control more?
Hi Jimmy, thanks, great vid. Question: can I connect all in the same manner to the Märklin 3-rail AC system? Thanks!
What are the main advantages, other than the WiFi support, over DCC++ ?
What are your thoughts on just getting the Arduino Mega with the ESP8266 built onboard?
I understand that can work and would eliminate the extra shield or flying wires for an external ESP8266 chip.
So does this replace a dcc controller such as a Digitrax etc. so you’d just wire that up to the bus?
I'm probably asking a question about DCC++EX Basestation that someone has answered and I apologize profusely. My memory is not what it has been lately.
I want to run DCC++EX Basestation on my modular N scale layout. My layout is a combination of Ntrak with the 3 main lines, branch and the mountain line and a series of modules that are oNeTrak with mountain line *.
Will I need to build a DCC++EX Basestation for each line or ?? I think when ready for shows I'll be operating a combined layout 36ft x 24ft or so.
I need the correct websites addresses for DCC++EX main and any other super pertinent websites etc as I would like to add signals, transponding, more locomotives, consisting, and more.
Thank you
Rob
Hey Rob! No worries! DCC++EX is like any other DCC base station. You will only need one and then connect feeders to other modules. dcc-ex.com is going to be your best bet for info.
Need a little more help here, not being an electrician and new to these little circuit boards I'm trying to determine how you know if you cut enough of the VIN Connect to isolate the power from frying the Arduino? I have used an Hobby knife to cut between the contacts but not sure how to test it.
Hi,
I using my train model to bring food to the table in my restaurant, but the guy that programs our software did failed and we have to many bugs to continue to use his software. we need to start from scratch and the solution you give in this video seems interested. Is it easy to link this DCC system to a custom app that will be able to select a specific train, send it to a specific table, stop 25 seconds and comeback to the station. It seems simple, but apparently is not. Do you know how much it should cost to program DCC++Ex to do such a thing?
Considering I was thinking about shelling out $$$$ for a Digitrax Zephyr on my small N scale setup; this is amazing
Would you setup a discord or something so we can pester and ask questions?
ive been wanting to get DCC but cost has been the killer
Good evening
I would like to know if it is necessary to wire the Wangtongze Wifi shield before downloading the DCC++EX program.
Thank you for your reply.
So what changes would you make to the hardware and wiring when doing this on an h.o. scale layout? Should i use a bigger power supply? What size is too big? Also with a dcc++ ex setup do i need to wire the arduino to a buss and then run feeder wires every 3 or 4 feet to the track like a normal dcc setup? Lastly what if i need more power for my dcc setup? Can a power booster be added to something like this? Most of my engines are old athern BB engines that either have already been converted or im converting to dcc sound which draw a little more current then most of the newer engines
A good 16 to 18vdc 4Amp+ laptop power supply works well with HO scale.
Yes just to wires from DCC++EX terminal A {Main} to a normal DCC wiring Bus with drops every few feet would be preferred.
Multiple power Motor Boards {boosters} are available like the IBT-2. for 5amp or more.

What is the easiest way to get the ESP-O1 Wifi Module working? like a step by step. I'm assuming I will need the Arduino IDE to program with?
Awesome video! I have an old analog train layout. Is there any easy way to change to DCC? Thanks
Usually my eyes glaze over when talking about electronics. This was not so bad since it is the Lego approach of snapping blocks together. Thanks and rail on!
yeah, as always it is time or money, put in the time or pay more.
not sure if it's been pointed out to you or not, but at 9:50 your mask on the network name does disappear briefly
PS when uploading the file to the Arduino Mega there was two green leds one was flashing until the sketch was done uploading and now there is one led a steady red near the reset button
How did you make the Y adapter for the ESP-01 jumper?
I have one question regarding your use of WiThrottle. Are you connecting to your Arduino Base Station directly through your home WiFi network, or to JMRI tethered to the base station via USB? I am asking because the project I have in mind is to build a coffee table layout and hoping to connect that railroad with as few electronic components as possible ( i.e. only one line of power to the coffee table) wirelessly.
So far, I have only connected to a test loop with your base station set-up through home network and JMRI. I had to have an I.T. friend help me set a special open port to get through my lap top's firewall software which had us stumped for a while, LOL!
With DCC++EX you can connect to the base station directly. No computer required.
Awesome, thanks for that ! What is the app name pls ? Can't find it on play store. Thanks !
Thanks Jimmy. Awesome instructional vid! Did the guys at DCC++EX happen to mention anything about using this setup with more than 1 throttle/phone at the same time? Running two locos each with their own throttle.
Yes! Max of 4 to 5 connections.
This is awesome (I'm planning a Swiss N Layout). One question.......what about electrofrog turnout polarity? With a point motor, can DCC++ change the polarity? Lots still to learn!
PS : Subscribed!
I don't understand. Can I use an Ethernet shield? Or, does my phone connect directly to the Arduino, and not through my network?
This ain't easy for a beginner. I'm hung up on a couple things. I have a main track. Is it a must that I have a programming track? Are power supplies and track all connected and powered up while I'm trying to load the programs? My wifi board from Robotshop somehow got a wrong zip code and was delivered to a wrong state. Can I set up without it using my laptop for control?
I have to wander if the Arduino Giga R1 with Wifi and BT with the Arduino Motor Shield Rev3 would make a good combination for this build.
Thank you for this great video! This looks like its going to be somewhat challenging for most folks to undertake. I am excited about the possibilities. Would a raspberrypi zero W be able to provide the wifi? I guess you would just use jmri at that point anyway.
I’ve actually tried a raspberry pi zero w with JMRI. It works but it’s pretty slow. If you can upgrade to the RPi 3. That works great!
Good Morning, after putting this wifi card that you show in the video is it necessary to have some programming for it or not, just connect and connect the wires?
How many HO locomotives can run with the recommended motor shield?
thank you i needed a better understanding i so need more information thanks
What would be cool would be to have the ability to attach potentiometers like MiniDCC to act as a normal throttle rather than having to use a mobile phone app.
I've been waiting for this to come out for years, I bet it's been out for a while already 🤣. I think your censoring of your WiFi SSID went away for a sec, too. Just letting you know.
I can't get dcc++ working, did as per video, engine goes slow around test track, jmri looks like it finds the loco but no control, help
How do we set-up this for JMRI? We would like to use this on our programming track station only
When you start up JMRI you select DCC++EX as the command station.
The DCC++EX command station was very appealing to me just starting out in model railroading. I am a goober at electronics, but your video instructions are excellent. Thanks. I followed your instructions and those of the DCC++EX website using an Arduino Mega R3, Arduino motor shield, and Makerfab wifi shield. However when testing the locomotive using the JMRI and DCC++EX web throttles, all that I get is the engine startup and idle. Lights, bells, horn, movement, etc do not work. Not sure what I did wrong. My voltmeter says that the power to the mainline track is only about 12mV. I thought that my motor shield was bad, so I got another one. Same result. Seems that there is not enough power getting to the tracks. Any suggestions. Goober
I'm completely new to DCC, but not to electronics/ programming. I think DCC uses Pulse width Modulation to supply power to the track, so you can't accurately measure the track voltage with a voltmeter. I'm sure others will chip in if I am wrong about this. Good luck.
