I wanted to make an audio player using an arduino but I didn’t have an microsd card reader or an mp3 decoder chip.
I managed to make one, using an micro sd adapter and wav files (8bits/8000hz)
Of course, the audio quality is bad, and the arduino can only read the wav files, but this gives an nice retro charm to it.

Next time, we will see how to make a gps logger! So don’t forget to subscribe to my channel !
SD card works in 3V! Use an arduino mini pro 3V to do this project!
