Arduino for Lego Trains #14: 433Mhz Wireless Communications
ฝัง
- เผยแพร่เมื่อ 12 ก.ย. 2024
- Send signals from a trackside Arduino to another Arduino on your train, using 433Mhz radio transmitter and receiver. This tutorial shows you how to use the VirtualWire library to send data wirelessly, and how to replace the Power Functions infra-red receiver with a dedicated L9110 motor controller.

Were all waiting for your big return :)
I've checked maybe once every 2 or 3 months for 4 years to see if I've accidently missed a video... and will continue to
i just remembered this channel existed, and now i'm sad there isn't anymore
Only found your videos now while looking at adding arduino to my model train projects. Putty you are not active anymore as your videos and explanations are very clear, informative and with just the right amount of humor added. I will be referring back to these videos regularly as I now start my aurduino journey. Thank you
HEY!! PLEASE COME BACK!!! :-)
The more I watch your videos on this channel the more I am impressed with your elegant (efficient and effective) teaching style. Your videos on this channel are superb.
If you wanted to promote your videos further perhaps you might post some of your projects to Instructables and/or an appropriate subReddit or maybe even contact Khan Academy.
Thanks. Making tutorial vids is part of my day job, so reading comments like yours helps me take pride in my work.
My pleasure.
Love this train series.
You have nearly 5 000 000 views! That's a lot! Why don't you make videos anymore? Why?! Imagine your every subscriber as a people all in one room. And everyone waits for your videos! Please consider recording new videos!
When are you going to upload a new video????
Well, nice to see motor driver works with PFs. I was experimenting with l239 trying build motor driver from scratch, but i am too clumsy with hot iron :). This same board was delivered to me last week. My idea was control that board with ESP (8266) . I have made experiments with IR reciever in past, so i will stick with this for a moment. May be i will give 433Mhz chance later.
Thanks! Just remember that the L9110 board only has two pins to control speed (both PWM), while the L239 (and L298N) boards use three pins: two digital for direction, and one PWM for speed. I use both types in this tutorial, so you may need to modify the code depending on which you use.
Thanks for the hint. I will look into it.
I am curious as to why you use the motor controllers you use in the different circumstances..
I am looking at what motor controller to use in the train itself with the arduino nano or digispark and 433Mhz reciever..I am thinking to buy the smallest footprint of motor controller I can to squeeze in the smallest of spaces..(eg Hogwarts train)..But I notice you use the controllers with a heatsink in your "box" to use with your switches, but use the l9110 in the train itself..Does the controller in the train get hot after extended use?? This would be a problem as it would melt the Lego I guess! Thanks..
Oh also while I'm here....For multiple control of trains I am thinking of incorporating an ID into the message the master sends the controller in the train?
And I was thinking if you have more than one trainwandering around your layout, using a colour sensor which picks up a coloured tile under the train so it knows what train is at what place/switch etc..
(i.e pairing up an LDR with a colour sensor) What do you think?
"used to steal the stereo" ... lol .. Love your videos!
So next episode?
Awesome Video and explanation!
Very interesting! What would be the range? My SBrick certainly doesn't have enough range using bluetooth.
During tests I was able to send signals between the Arduinos across 10metres, through three concrete walls. So it's definitely stronger than Bluetooth. I don't have any more space to test the maximum range!
Thnx for letting me know! sorry 4 the late reply, like you probably know youtubes messaging system isn't the best out there... *sighs... I am now experimenting with NRF24L01 modules for more range.
Max. of this is 50M!!!
When is the next video? Love your tutorials! :)
I've been waiting too!
I'm also waiting. I just love these videos.
is he still around? it's been awhile now ='(
That is brilliant. Exactly what I was looking for and is this weekend's project. I'm a newbie to Arduino and only started last week, so would this project bit too much for me ? Would also be interested to see your views on the 'Ultrasonic' detector and how accurate it is. As part of my bigger theme, I am looking at my Train pulling into a siding and using the Ultrasonic detector to bring it to a halt at exactly the right spot, as I will then have a Container crane unload one of my wagons which are actually going to be converted to battery packs, and replace it with a fresh battery pack. Ambitious I know.
Thank you for this most excellent video
please come back
I notice your cables are quite short, did you create (crimp) them yourself? i am cramming motor controller, digispark and wireless Rx into the same train as you but trying to get it all into the part in front of the cabin and behind..part of doing that successfully I think is shortening and managing cables as well as possible!
+Angelo Giacon I make all my own cables and yes, it's a very tight squeeze.
when the new video will come out?
i think he died 2 years and still has not made video
Kids, mark your cables before cutting them.
I want to control multiple trains at once😥
Wow! Thank you!
R-I-P wires
Could you cover the new generation of lego trains (2018) that come with a bluetooth receiver? Thanks!
Same problem here, no way to found a solution to control them with an arduino.
Hey Andre...if you're inbterested in controlling the new "Powered Up" series of trains, go ahead and google "Legoino" or just "controlling powered up with arduino" and you'll find all the libraries for arduino as well as some tutes..
Why did you end this series?
your very smart
i need somehow to do it for 12v tracks of my old lego sets, but i dont have any ideas how to esp to run them seperately
You need something to grab the power from te rails or use batteries. As for the motor, you can use the ones with plastic wheels or simply replace the metal wheeels with plastic wheels.
Hi
In one word: “awesome”
Your series of video are very good and your explications are very clear and understandable
Can i suggest you a very cool way of wireless communication?
There is a module: D1 (esp8266) arduino compatible
Its a wifi platform on witch you can code with arduino style.
And there is a free app: Blynk.
With witch you can connect to it and connect one node to another
Very easy to use and very cool
If you wish to make a new video with it, i will love to help you with it
Come back!!!!!
what is this app?
Where can i find the codes?
Thanks
SBB lego？
Perhaps you might consider including a link to arduinolegotrains.wordpress.com/ in the description of this video as well as in description of past and future videos (when applicable) on this channel.
Future videos will definitely include the link!
I am glad to know that.
Using Arduino for Lego trains or anything else in fact is a waste of money. Arduino is good for lighting a light with pressing buttons etc. But for real projects it is absolutely useless.
which controller is ggod for real projects?
I am not sure what you base that assumption on, since using RF receiver and digispark costs like $3 whereas buying Lego stuff to do the same costs like 20 times that..(at least)..please elaborate?
