This short video shows you how I set up an RF transmitter and receiver on the Arduino. It also explains how to encode/decode a string.

• INVESTIGATING: The Ran...
For anyone confused why the antenna should be 17,3 cm long ... its because it is approx. 1/4 of the wavelength of the carrier wave which is the optimum antenna length for transmission and recieving.
Size matters
For those who use Uno (16Mhz) and mini (8Mhz) like I did, remember to set your uno speed to half. UNO: RH_ASK driver (1000, 11,12,10); Mini RH_ASK driver (2000, 11,12,10);
Cant understand.
The out of sync audio kinda throws me off during the coding a bit. :')
wait so it is data vcc and gnd? I've put vcc on data and data on vcc then. but it still worked. now i tried it like in the video and it still works fine. What is this now, how is it possible?
Hey dude! You have many good videoes, but i do not understand why you don`t invest in a better microphone? The sound is pretty bad.
Great video, but my circuit doesn't seem to be working. Could it be because I'm using a Mega instead of a Nano or Uno?
What gauge wire?
@AntonyCartwright when i download the .zip file from radiohead and follow the directions for putting the library into the sketch, ask_transmitter and ask_reciever dont show up. is this a problem with radiohead or can i fix it somehow?
Thank you Antony. I've just started with Arduino and my first simple project is to use this module. I've found lots of detailed coding but no one who has simply explained how to add the code to the library, until I found you. So far I have only installed the library and not set the circuits up but I'm already exited to finally get this far. Thank you John.
*important note*
I came here because I was looking for answers. You answered everything. Best voltage, best antenna arrangement, what about curly ones... All answered in entertaining informative content. Full marks. As a 23 year experienced software engineer your explanation of a const will stick with me forever. Legendary. :)
I am using a raspberry pi but I still watched this for information and I wanted to comment that this is one for the better videos as there is no music over the voice (what a pleasant change) and it is also fully explained well
I struggled with this for like 1h but this video help me a lot! Thank you very much ❤
Just to test it for myself, I put those little coil antennas on and got a few feet of distance! Made the length wire antenna you suggested and it's great! Thanks.
This is brilliant, thanks! I acquired 2 sets a few years back but at that time there were no libraries for them, and I had to write my own basic drivers for them, using them like a raw serial link was dodgy at best for me. This will let me get a lot more use out of them.
Do you know what I love about your channel? the content you create is practical and actually informative and useful. Keep it clear and easily understandable, cheers 👍
Thank you so much for this! I am currently using this module for a school project and I was not able to get it to work as needed until I got to this video.
Very good tutorial, thanks. I ended up using the HT12E and HT12D, encoder and decoder chips, to process the serial data into bytes, check address etc then connected the data busses, xmt and receive to Arduino pins, works well. You commented the code was unnecessarily complicated, with these chips no library is needed just pinmode settings, digital write and read. The decoder chip has a VT pin, valid transmission pin you can monitor in the loop section to see if a transmission is coming in.
