This is a demo of the famous RCSwitch library been around for almost 10 years.There are tons of tutorials and examples
on the Internet.With wiring diagrams and source code. Also ported to Raspberry P.
Thank your feedback
thank s your video !
thankyou so much It works😃😃👍
Thank you. Hope you have a good project
Hey
Not a bad video, thanks for sharing.
I've had a play with the RC Switch library and have created some interesting projects. However, the library doesn't read rolling codes from common car key fobs. I'm planning an looking at and tinkering with the library code to make this possible (probably above my ability). Do you have any experience in this area?
Hope you done it
@@ALPHALabs02 never had much luck with it.
The project was kind of a 'just because' and the effort involved eventually outweighed what I would have got from it.
Thanks for getting back though. I might try again at some point.
Rolling codes use secure cryptographic encoding methods. They are designed to be uncrackable. I think you might be wasting your time, unless you have a millenia or two to spare.
Haha, thanks. It was a while ago when I commented. I was hoping to just be able to receive them, see them and maybe replay them rather than decrypt them. I had 'some' success, but found it was taking up too much time for what would ultimately just be a novelty. Thanks again though.

You just get the signals by an SDR device its called software digital radio. The flipper zero kinda work like that but its not cheap. 300€. There is a USB dongle device called "rtl sdr" for around 30€. I have one and it works great. Have fun ;)
I'm struggling to replicate an RF remote signal which I'm told is on 16mhz frequency. Could I decode that using these instructions? I see 433mhz as typical RF signal.
Thanks for sharing.
Does this library work for custom made Rf transmitter? (No remote control)
How to set the bit length to receive?
Sorry friend. This video is created when i was a student. I didn't updated information of this library un a long time ago. I am not sure to say anything about it. Hence, I can't give you advice. Hope to you find from another videos. Thank you
Thank you for the video! I am using an EV1527 trasmitter but the monitor doesn't log the buttons. I use wemos D1 on D4 which is the #2. Any help please?
Sorry i haven't tried it yet
Cara eu apanhei com essa placa tambem, GPIO1, 3 E 16 nao funciona com interrupçao, nao funcionou comigo. Minha placa eh a D1 R1! (Isso daria pinos D0,D1 e D2) use os outros pinos!
E coloque no codigo o pino como o correspondente em GPIO, nao como D**!
Procure por Wemos D1 R1 pinout, vai entender!
Comigo funcionou, depois de uns dias de pesquisas kkkkk
Hey !
Thanks for the video. Very enlightening. I tried to do it with remote control (RF433) used in residential gates, with 3 keys, but it didn't work. Can you tell me if this example doesn't work for some types of control?
Hi, my friend. This is a video that is created a long time ago when I am a student. I am only checking with a typical remote. Hence, I afraid I can't help you
@@ALPHALabs02 No problem, thanks so much for the reply and help. regards. Bruno.
@@brunowolfpack6767 did you ever find a solution?
thanks a lot
Thank feedback
Great tutorial , but PLEASE lose the annoying computer voice
Thank feedback
@ALPHA Labs I hit a wall. I purchased a 433 Mhz 4 chanel receiver and have a 433 Mhz remote. To make sure they work together, I wired an led to the receiver and am able to control it with the remote. Next I wired data D0 of the receiver to D2 of the Nano and off course ground and Vcc. The Nano works fine and I have used it prior to this for controlling led lighting. Once I uploaded the Demo_Advanced, I expected data on the serial monitor but just have a blank screen. To make sure the monitor works, I inserted a println statement and that shows up in the monitor, but no data from the receiver. I also made sure the receiver is encoded with EV1527. Any ideas?
Sorry for late reply. Hope to you resolve your problem
@@ALPHALabs02 It may have had something to do with the receiver. I purchased a single channel kit like your video shows and all is well.
Thank you soo much, I watched soo Many videos on 433Mhz RF module this is best.
Thank your feedback
Will these work with a garage door opener remote? I have tried with 6 different remotes and now 5 different 315 mhz and 1 433 mhz receiver. Also an arduino nano and an 8266. I do not get anything to display in the serial monitor. I have tried 3.3 volt and 5 volt pins and all the digital pins. What am I doing wrong?
I hope you done it
Do you manage to do it?
I got it to work with a range of 1 foot. Very difficult to get it to work. I will not try this setup again.
@@mschaffer2826 ok, thanks
I would like to use this method to do the following. When I press the remote button the first time, it turns something on, an LED for example. When I press the same button on the remote again, it turns the LED off. I know how to do that with a physical push button connected to the Arduino, but am not sure about coding it when dealing with the data received on input 2 through the remote receiver. Can you help me with that?
5:25 ...it will help you doing so..
@@haseeb7027 Thank you, I somehow missed that. I'll take a look at it tomorrow and hopefully make it work.
Still having a difficult time making the same button press turn on, and a repeated press turn off. I can do it with a simple push button, but not when dealing with the data from the receiver module. Being a beginner, I'm not sure where to go from here.
Hope you done it
Hello, this is a video.
You can see that it works with the RF receiver 315Mhz-green.
I have a question here.
I wonder if this project is possible with the NRF24L01 module I have.
I am trying to upload a program to Arduino by sniffing the automatic door.
I am really happy because you like this video but I have never worked with NRF24L01 before. I think there will be videos like that on TH-cam
Can I use this RCSwitch library for 2.4 ghz rf transceiver (nrf24l01)?
Sorry i haven't tried it yet
You do realise you can tune the little slug capacitor on the receiver to change the frequency you do this by keep pressing the remote but have the remote far away as you can and turn the tuning slug until the led blinks alot and turns off for a second. Now what is this led you talking about well you connect any colour led (I used yellow) and you connect the led to the receiver ground and to one of the data pins any and you should be able to change the frequency of the receiver. Feel free to ask me a question about this
Is it possible that i make a device that can automatically find the RF? Basically like a universal remote for all devices that transmit with a radio frequency. Thanks
Thank you for sharing this video. The transmitter/receiver kit I bought says 4 channel. Can I still decode a 10 button remote and have the Arduino respond to all 10 buttons?
If the frequency of remote is matched to the frequency of receiver, it will receive data.
Data of receiver is transferred to Arduino by wires so that 1 or 10 button isn't problem.
The important thing is to match frequency between transmitter and receiver.
@@ALPHALabs02 Thanks for the quick reply. My receiver should be coming in the mail today. Everything is set up. Fingers crossed. Would you mind if I did a tutorial using your method on my channel? I would off course link to your site as the originator. I think my subscribers would like this.
Ok. Don't worry about it. No problem
Nice brother
Thank
Hello thanks a lot sharing this video , can you please share your code, switching is toggle mode ( same button is using ON and OFF)
It depends on your code
hey good job.can u do another project.connect 4 button arduino and send coomand to rf receiver circuit?
Thank friend.
can we use it for car key fob ? they have rolling code
Sorry i haven't tried it beforce
Hi, I want to use nodemcu card which pin i need to connect RF data pin? Also is it possible to use any pin or i need to use only one pin? Thanks in advance!
The data should be connected to interrupt pin
Tui không nhận dc kết quả gì hết. Tui dùng bo esp8266 vẫn không được.
Thanks for sharing this video. Can you help me, and give me CODE for controlling 4 leds?
Do you want control 4 seven segments led?
not working for me :< tested on many many modules, original Arduino Uno, Leonardo and some clones... i get nothing in serial monitor... do you have any idea what to do?
1. You must sure that RF remote matchs frequency with RF receiver board.
2. You must sure that connect from receiver board to Arduino is true.
Hope to help you!
@@ALPHALabs02 *make sure
Video was too good
But can we transmit that decoded rf value
Yes. TH-cam has many video as you think
@@ALPHALabs02 thx for the reply but i didn't get such video can you provide me video link
Can I use my Car key for this?..my car key remote has 433mhz ...so, is it possible?
I am not sure about it. You can try,
Hi, I'm trying to receive a signal from my gate remote 433,92 MHz with the same receiver that you have, but my Arduino Uno seem to not seeing the signal at all. What might be te problem ?
This project was so long ago, i am not sure that this libraries is available at now. Can you check this issue come from software or hardware?
@@ALPHALabs02 I downloaded the latest version of the liberary rc-switch and I used an example from it, so I think software is ok. Actually I bought this receiver in a set with a transmitter and toghether they work well, so I don't think this receiver is defective. The problem is that transmitter requires another arduino board and it's not very practical for my project - I thought my gate remote would be perfect. But like I wrote before , serial monitor displays nothing when I press buttons on remote. I have no idea how to solve that...
I don't understand I followed everything to the letter but I get ZERO in serial monitor. Is it sometihng to do with the fact that it's two sketches in tabs?
I hope that I solved it
Hello can decode Tire pressure sensor?
Sorry friend. This project was so long ago. I did not anything about it. I am not sure about your question. I hope you can find an another answer
Can you please tell how to reproduce the signal that is captured with Arduino only?
Can you show your purpose??
@@ALPHALabs02 Basically, I am a Pentester or a bug bounty hunter. I recently bought a simple drone (of 6k Indian Rupees) with basic features and wanna conduct a security test on it. I like mcu because those are flexible and can do whatever I need (I have NodeMCU). In simple words, I wanna capture the signal from RC and then reproduce it to test if I could control the drone, are those encrypted, and so on.
@@shriyanssudhi4545 About your drone, I don't know which it's frequency. Often it is about 2.4Ghz, I'm not sure about it. I've never done such projects so not sure to advise you. You can watch videos from another TH-cam channels. Good luck!!
Hello dear friend .... Why in the code is the text "output" because ich this text is in there the program is not compile ich the text I remove of this code the program is compiling .... can you send me some info ...thank you
Hope you done it
Can u share the schematic and code details
You can make it if you watch the detail in this video.
Where can I get the code for these sketches? I can't see the whole code in the video because your camera is blocking half of it. So I can't even retype it if I wanted to.
This project was long time ago so I do not store the source code. Although I can’t send it to you, I think that you can retype it if you want. The source code is easy to see and retype. Hope you can do it
bro! how to generate code from Arduino (or Wemos 8266) + Transmitter for Remote learing code ( It doesn't have code)? thansk a bunch!
Thank for ask. It is a another topic that I haven't done it before. I think there are many youtube videos that relate to it
@@ALPHALabs02 i have tried looking for on youtube but don't have result. If you have times, equipment and willingness, can you proceed that project ? thanks very much!
Hope in the future
After decoding, how can i replicate this signal ?
This type of remote is fixed code so you can't...
how to send these signals back to the receiver device
Sorry, i'm busy. This type of remote is only transmitter
I could not read what is on the screenshots - too blurry
Select video HD 1080 please! I think that it's ok
Not working for me either.
Hope you done
Can you give code and dragrams?
Sorry. It is a long time ago but i can make it with this video. It is working
I don't get any output in my serial monitor. Is it possible that intrupt ports are different on a wemos d1 esp wifi board?
Hope you done
Sim na wemos tem que usar outros pinos, o que voce coloca no codigo tem que ser o correspondente ao GPIO da wemos... procure por wemos d1 pinout!
E nao use GPIO1, 3 E 16!
I really don't understand why so many are asking for the source code??? Am I not understanding this correctly or is there some other code besides the code in the video???? If it's the code clearly seen in the video, what is preventing someone from copying 24 lines? Again, I must be missing something, because it would be mind blowing if people are too lazy to copy 24 lines of simple code????
Indeed they are just too lazy. It's the new trend: do it for me so I can pretend I did it myself.
Thank feedback
@@longdongsilver4719 perfeito!
