Is there a tutorial to play music (WAV file, whatever) on an a micro SD card, through the ESP 32? I found several libraries that enable this on an UNO or NANO, but they won’t work on an ESP8266 or ESP 32??
Unfortunately, I’ve never experimented with audio on the ESP32.
However, I’ve found this library that should work with the ESP32: https://github.com/earlephilhower/ESP8266Audio
I hope this helps.
