For the remote MP3 Player project we used:
- 1 – power module with battery
- 1 – littleBits wireless receiver
- 1 – littleBits MP3 Player ($50)
- 1 – littleBits synth speaker ($20)
We created wireless remote to have a dimmer bit to control the volume and a littleBits button ($8) to change the song.
On the MP3 Player module the mode switch needs to be set to next to enable the remote button switch to change the songs. Finally we connected a speaker wire between the MP3 player and the speaker module and we duct taped the batteries to the bottom of the mounting plates.
