Control MP3 player via RC
 

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...

Hi...

Some news, the construction wasn't very effective, the contacts often didn't close when I played with the function channels. In addition, the cabeling sometimes broke and I had zu renew the soldered contacts.

So I decided to search for an alternative solution and I found a shield from Adafruit, the VS1053 MP3-Codec shield. It was exactly what I was searching for.

Here's a link to the product Adafruit VS1053.

In addition there's a great tutorial for the shield.

The board has changed a bit.

The control is the same, but the "Previous" function is removed, it wasn't needed.

Now that it's working I'll place it into the Black Devil.
