I wanted a cheap and simple way to play a single MP3 file (0001.mp3) in a loop when power is applied to it. I came up with this.
Used a DFPlayer Mini. I added a 5V + to the VCC, Ground to GRN, and a 3omh speaker to SPK1 and SPK2. The problem I found was that you needed to Start the player after power was applied.
I solved this by jumping ADKEY1 to GND (10 pin). This seems to work great. Any issues I am missing?
No, I think that's exactly what's supposed to happen.
