Control MP3 player via RC

[gismow]

Hi...

While my Black Devil is nearly finalized, I want him to play also some music while it's driving. So I started to search for a solution to control a simple MP3 player via RC.

First I started to search for a small and cheap MP3 player.



Is was disassambled and 2 cables soldered per function.





After that I soldered a small board with an ATMega328 processor. It controls the functions via a NPN transistor.

The programm listens on 2 channels.
Channel 1 : Volume + / -
Channel 2 : Play/Pause, Next and Prev song





And it's working as expected. Here's a short video to show the functionality. I beg your pardon that it's in german, but I hope it shows that functionality without the need of my bla bla...
