My favorite part of this was where you showed how you increased the battery life/efficiency of your remote. I probably won't build an RF remote but learning about that was really useful. That's why I love these videos, you never know what you're going to learn.... Thanks!
I"m not an electrical engineer or electrician but in my opinion you design the most elegant and efficient circuits I've seen. You must have too many ideas to implement.
Awesome stuff. That gave me an idea that I'd like to try. How about grabbing the signal to the IR diode. It would be fairly straight forward to write some arduino code which would translate all the key codes to RF signals. That way we could convert any standard IR remote into a full blown IR/RF remote (given it has enough space for the Arduino).
GreatScott! Hey. So does Xbox controller use RF signal. Sorry I am not pro on electrics. I see ur channel because I just love seeing chips and motherboards LOL 😂
I am currently undertaking a project of making an rgb strip controller for my PC with an arduino and 3 mosfets. I'm using USB and serial commands in visual studio to make a programme to control it and it's going well so far. Love your videos
Very interesting project! Nrf24l01+s are easy to use and cheap RF modules. Still the bag of them that I bought some time ago is still gathering dust somewhere... Time to create something with them! Thanks for this inspirational video!
To anyone wondering what the diodes on the switches are for, they form an OR-Gate to pull down the single interrupt pin whenever one or more switches are pressed. Without the diodes, you'd just short all the switches together.
The diodes were added to provide a single output from all of the switches without affecting their original purpose of providing 3 separate outputs. So now there are 4 outputs from 3 switches, one of which is when any switch is pressed.
Hello, at 5:24 about the measurement of the current consumption(15 microAmp), Are you connect them in series (power supply to nRF24) and get it? Or need to take some step?
People with higher IQ tends to accomplish a task in a more complex way. But that doesn't mean its the best choice. I rather could have done this by using nano as real time logic analyzer by connecting to IR-LED and sending the resulting byte code over NRF thus in this way all buttons will be functional and you dont have to damage IR side also the remote controller so we could have both available always. Thanks for the effort keep up the good work mate.
Extremely useful! I've had this idea before and now I know how to do it! One more thing I've been thinking of is how to control multiple strings of leds. You can use any remote so it's as easy as programming multiple inputs to one output like a different t.v. remote and buttons, for more than one room. So like this video says you can just code the remote outputs. Say there's a few rooms, so the "AUX on" code (master remote for tv, dvd, aux, and cable) with the kitchen t.v. turns on the kitchen lights only, however not the living room lights. The living room t.v. remote only turns on the living room lights, however the "TV on" code for the living room remote will turn on the kitchen lights (TV on for living room does not affect kitchen t.v.). My question is how would you control the different room leds? I was thinking a couple or multiple RF receivers and one power source. If it was just a big circle of leds and they had a way to turn on or off certain sections. So the kitchen receiver could control all the rooms lighting from one remote and the controller would power the entire string of leds, and at the same time, each individual remote can control each individual room of leds.
Just an idea: How about hooking up the arduino to the IR led and analyze the signal? Probably you could use any button (or button sequences) without ruining the remote control's circuit.
What are you using for bus wire on your perf board? I found dollar store racket shaped bug zappers that have the perfect size wire. They are cheaper than going and buying a spool of the same wire.
Great video. Came here for advice on another rf project including a mini, which I got. But thats a cool project which is going on the ‘to do list’. Cheers
You talk about power consumption and how you lowered it. Would it also have been possible to use an ATTiny or two as they use less power than an Arduino?
When is the drone project going to be done? I am working on my own for a high school senior project and want to see what yours looks like. Mine is 3d printed with a red/black/clear style.
what's up Great Scott. I was wondering if you had any issues with the nrf boards because I've had these for a while and its always hard to get them to communicate. do you have any suggestions???
Ich hab gestern noch erst nach Bauteilen für ein ähnliches Projekt gesucht und dann heute dieses Video ... Wie stark ist die Reichweite damit? Sind Wände ein Problem?
Laut dem Amazon Link für das Teil "nRF24L01+" "Communication range up to 329 feet (100 meters) in ideal conditions.". Denke schon das es dann zumindest durch eine Wand gehen sollte, evtl auch mehr.
GreatScott spricht sehr wohl deutsch. Aber egal. Die Module funktionieren sehr gut. Dazu kann du sie auch noch im high power Modus betreiben. Funktioniert bei mir durch mehrere Wände im Haus. :)
Thanks ! I was looking for neat transmitter and receiver for my Arduino RC formula. I was using 433Mhz transmitter (because of antenas, that were on remote and formula) but I imediately ordered the 2 2.4G transmitters and ll upgrade it soon :)
Hi! What's the range on these things (in an average flat)? Is it any good for home control? Wifi sure is a common oprion but also relatively power consuming one. BR!
Also, I'm confused about the 47uF, as the official Doc from Nordic invites to use a 4.7uF: "Mounting a large surface mount capacitor (for example, 4.7µF ceramic) in parallel with the smaller value capacitors is recommended." I personally had initially put a 1F (5v) which I had at hand for my tests, as if you put none it just doesn't work. So I'll try with a 47uF (in 5v) next.
What is the range of nrf24l01 inside a house. I find it's very less. If we walk with the transmitter there is package missing in between. And it seems it's fairly directional too. Any ways to improve this.
Wow! Das ist einfach genial! Ich blicke zwar noch nicht komplett durch, aber das ist ein Projekt dem ich mich mal widmen werde :) Was für eine Reichweite erzielst du ungefähr mit den nRF24L01+ ?
Hi do you undertake private project work I have a three channel 433mhz transmitter but need it to control an IR receiver but dont know where to start I have the original IR transmitter as well any sugestions would be good and could pay for the work.
Is it possible to program the rf component with an access address? for example: if I have one transmitter and few recievers and I want to send data to specific reciever
@ next Q&A: 1. Ever heard of the Kossel Rostock G2S 3D printer? 2. Do you want to built a bigger CNC mill in the future? 3. Can two beds in one room communicate wth I²C ? 4. What were your grades in school? 5. What projects did you do before TH-cam? 6. Do you have a coffee machine that can weld together a bag of coffee? 7. Adam Savage or Dave Jones (eevblog)? 8. Have you ever got into airsoft? 9. How long is your "to do list" 10. Can you post more often photos on social media?
scott, i have that kind of led controller, actually I have two but I think they have the same frequency that is why I cannot use them simultaneously, How can I Adjust the frequency so I can use them both. because they can share on one remote. thanks
hi scott !greetings from argentina(an apologize for my english i hope you understand me ).So from the remote you only took the buttons,the signal that each one makes and the supply.. is that right? awesome job keep it this way I love what you do
I saw this module months ago, and now tons of people is uploading videos about it. it makes me happy
Normal: 4 days
Edited: 7 years
Boy, that escalated quickly.
ya hahahahaha id be fine with 4 days but this is why GreatScott is GreatScott
@@theengineer9910 Hmm I dunno, 4 days to change your tv remote batteries sucks immensely.
My favorite part of this was where you showed how you increased the battery life/efficiency of your remote. I probably won't build an RF remote but learning about that was really useful. That's why I love these videos, you never know what you're going to learn.... Thanks!
OMG how clever Is this dude. I thought I was pretty smart but this is many levels above my comprehension.
same here
I have been searching for s good tutorial with the nrf2 for so long and the day has finally come.
This is one of those Great Scott videos that went over my head.
I"m not an electrical engineer or electrician but in my opinion you design the most elegant and efficient circuits I've seen. You must have too many ideas to implement.
One of my favorite tutorials yet. I bet your house is awesome with all these gadgets you build. Perhaps a tour video?
Awesome stuff. That gave me an idea that I'd like to try. How about grabbing the signal to the IR diode. It would be fairly straight forward to write some arduino code which would translate all the key codes to RF signals. That way we could convert any standard IR remote into a full blown IR/RF remote (given it has enough space for the Arduino).
Sounds possible
Great Scott you are awesome!!!
Rowyn Gaming official Yes you are awesome too!
Rowyn Gaming official and remember 1like = 1respect
This video pops up right after i finished my IR controlled lamp with the help of your previous IR video!
Great content Scott :D
Thanks :-)
liked before watching
Sarvesh Verma a greatscott video is always good ;)
That's pretty gay mate
Same here. I just do it to videos that I know I'll like.
no one cares
Mateusz Bugaj Y u no cares?
I like that you are always very enthusiastic towards the end! ;)
you went from 4 days of battery life to seven years. ...that's amazing
Could you do some sort of GPS Tracker project? I asked a few months ago, not sure if you remembered.
I am currently working on something similar. But it will take a while though.
Or how about 12v car battery applications? I have been getting into the electrical systems of my car and adding switches for certain applications.
GreatScott! Hey. So does Xbox controller use RF signal. Sorry I am not pro on electrics. I see ur channel because I just love seeing chips and motherboards LOL 😂
All console wireless controllers use bluetooth due to their low power consumptions.
Amazing how fast you are producing high quality content!
You are very creative man. Your projects are always awesome!
Another great project from the one and only Great Scott 🙏
I am currently undertaking a project of making an rgb strip controller for my PC with an arduino and 3 mosfets. I'm using USB and serial commands in visual studio to make a programme to control it and it's going well so far. Love your videos
even though i'm not planning making this I always watch just because I love your vids
That's what I call hacked! Great job!
Very interesting project! Nrf24l01+s are easy to use and cheap RF modules. Still the bag of them that I bought some time ago is still gathering dust somewhere... Time to create something with them!
Thanks for this inspirational video!
Great Scott: makes crazy stuff.
Me: gets exited about him having the exact same TV remote as mine.
How lovely. I just finished my RF project. It also had to do with turning on and off lights.
This is just pure genius, you are so clever!!!
To anyone wondering what the diodes on the switches are for, they form an OR-Gate to pull down the single interrupt pin whenever one or more switches are pressed. Without the diodes, you'd just short all the switches together.
This is great! I hope you have future tutorials on low power mode. Thanks!
great video! one question, what are the purposes of the diodes in series with the switches?
also, what are the implications of removing the voltage regulator?
The diodes were added to provide a single output from all of the switches without affecting their original purpose of providing 3 separate outputs. So now there are 4 outputs from 3 switches, one of which is when any switch is pressed.
Great idea, clear instructions, nice clear and concise video!
But I bet this project takes longer than 8 minutes to complete... lol
Yay more HACKED!
who said u should understand to like a video 😅
adam haklı amk
Wtf 5 years ago?
@@AliYassinToma uhhhh
Superb tutorial!btw: In transmiter module you should first put radio in sleep mode, then arduino.
I love your projects like this m8. Keep up the awesome content:)
see! you!! NEXTTIME!!!
genius guy GREAT SCOTT!
Sehr Informatives Video aber die Formatierung deines Programms macht mich wahnsinnig :D
I used this modules in my graduation project
, it's very awesome
Wow, I'm planning on using a pair of these exact RF transceivers for a DIY electric skateboard. Hopefully it works.
In theory they should work just fine for such an application.
Hey great Scott please keep uploading thank you for uploading videos I like to watch thank you
Hello, at 5:24 about the measurement of the current consumption(15 microAmp), Are you connect them in series (power supply to nRF24) and get it? Or need to take some step?
hey great scott can we use tv remote for rc remote car or something as a transmitter ??
Sure

You are simply brilliant, well done!
Great video. Came here for advice on another rf project including a mini, which I got. But thats a cool project which is going on the ‘to do list’. Cheers
Scott, what do you know about MAVLink?
Please add it to the list of things to do, if you know anything / can demonstrate it
Great video, as usual!

I don't know when it is done
Nice video. What is the maximum range of the transmitter??
I'm so glad I support you. This is an amazing hack.
Thanks
You, my friend, are the Arnold Schwarzenegger of hardware mods! :D

Great job, man! So cool!
You are the best! thank you for all the amazing content!!
What kind of wire do you use on the backs of your PCB's that you solder to to make straight lines?
no mention of silver-copper wire :(
I was thinking the same xD
PhilippeFrancais85 silver-cuuper wire
You are a wizard!
Good work. Useful!
Ich hab gestern noch erst nach Bauteilen für ein ähnliches Projekt gesucht und dann heute dieses Video ...
Wie stark ist die Reichweite damit? Sind Wände ein Problem?
er wird dir nicht antworten, wenn du auf Deutsch fragst
English verstehen doch mehr menschen als deutsch, wo ist das Problem?
Ups, falsch verstanden, sorry :)

That NRF24L can receive only another NRF24L signal only? or it can receive any 2.4Ghz signal from existing transmitter that not generated from NRF24L?
Is it only me who does not understand a single thing about circuits but still watch every video?
Woalid Hossain well I don't watch every video but I almost understand jack shit
I like these stuff so i watch every video
Thanks ! I was looking for neat transmitter and receiver for my Arduino RC formula. I was using 433Mhz transmitter (because of antenas, that were on remote and formula) but I imediately ordered the 2 2.4G transmitters and ll upgrade it soon :)
hi Great Scott its nice, Also we use bluetooth both the side to send the command ??
Hey, maybe you have worked with PADI ioT stamp ? How it is compared to ESP-12F ESP82666
Why are you using 5V Arduino Pro Minis instead of their 3.3V counterparts?
Hi! What's the range on these things (in an average flat)? Is it any good for home control? Wifi sure is a common oprion but also relatively power consuming one. BR!
hey great scott will you make anther q&a&c video.
thank you :D I was looking for a tutorial to build something like that for a while ;)
Thanks for your videos.
What about range of this project? *in building real life scenario
Is there some kind of kit that has a remote with a few receivers to wire up to things?
5:02 that resistor is RED HOT or its just light?
Nice as always. Thanks
can you add the voltage rating of the capacitator we use ? It says 47uf but i could not get what volt is it, (is it 5v?). :(
Also, I'm confused about the 47uF, as the official Doc from Nordic invites to use a 4.7uF: "Mounting a large surface mount capacitor (for example, 4.7µF ceramic) in parallel with the smaller value capacitors is recommended."

What is the range of nrf24l01 inside a house. I find it's very less. If we walk with the transmitter there is package missing in between. And it seems it's fairly directional too. Any ways to improve this.
If I could I will put a 1000 like, very nice job, thank you
+GreatScott! how far are these transmitters reliable for use?
what effect does this have on the remotes battery life ? did you have the arduino sleep the wake on a button press ?
Now, you need to modify your sound system remote with this lowpower lib. 👍👍👍👍
Wow! Das ist einfach genial! Ich blicke zwar noch nicht komplett durch, aber das ist ein Projekt dem ich mich mal widmen werde :)
Was für eine Reichweite erzielst du ungefähr mit den nRF24L01+ ?
Hi do you undertake private project work I have a three channel 433mhz transmitter but need it to control an IR receiver but dont know where to start I have the original IR transmitter as well any sugestions would be good and could pay for the work.
isn't it neccesary to install an inductor on the FM transcievers? How mach range can you get from those transcievers?
What do you do with all those amputated voltage regulators?
plz make a video adding a potentiometer to control the aperage of your boost/buck/boost-buck converters
nice video but for a remote especially i would use a 433 mhz transmitter/reciver
Wich oscilloscope are you using ?
Thank you in advance
Just wondering is the nRF24L01+ same as esp8826? They look so similar.
No
Is it possible to program the rf component with an access address? for example: if I have one transmitter and few recievers and I want to send data to specific reciever
It's not clear to me why you added the diodes to the buttons for the low power mode, whatt i'm missing?
How do you feel about those cheap 315/433 MHz transmitter and receiver pairs?
I used one of those for my electric longboard. They work pretty decent as well.
Thanks!
what are the benefits of switches pulling to ground rather than pulling to vcc?
