This is a simple project showing how to generate an AM radio transmission on 835kHz.
Audio2Header converts audio files to a c++ header
AMTransmitterI2S plays an audio loop. AMTransmitterI2SButton plays the audio sample on a button press.
You need an ESP32 module and a wire as antenna connected to pin 25
