Hello everyone
I have ordered a 433 MHz receiver + transmitter module.
When reading the signals from two 433 MHz remote controls, my Arduino does not display any read codes. Once, after several hours of trial and error, I had intercepted two signals. I installed the RC Switch library and also used the sample code.
I have the following modules:
