I am trying to play a single mp3 file from the DFplayer-mini-mp3-module via button control.
I only connected Vdd, Gnd and the speakers. On the SD card is a single file in the root folder named 0001.mp3.
If I pull ADKEY1 to ground, the file is played but then it doesn't stop and keeps looping.
Does anyone know how I can play a single file only once?
Many thanks and happy proggin,
