How to copy a 433MHz signal with an Arduino board

This method is very simple and only requires a few components: I used an Arduino UNO board, a XY-FST RF emitter module and a XY-KM-5V RF receiver module. The method using audacity is very simple too but requires some resistors: the output voltage of the module can go up to 4V so I had to decrease it with a voltage divider to 1V maximum (for the audio input of my computer's soundcard) This is probably a quite overcomplicated and long procedure that could be simplified a lot, but this naive approach of extracting data from a simple measured signal works in most cases. Note: the delays were measured with the time cursors in Audacity (I forgot to add this part in the video) Don't waste your time trying to read the code from the video ; if you want more information about this project or more explanations on the scripts and schematics, feel free to contact me on Discord (@Chacha#0209) :   / discord
