This one is for the Spotify people. We’ve created a small project that makes use of the Arduino and LCD Keypad shield to create a Spotify remote control. This will show the current playing song as well as adding Play/Pause, Prev and Next functionality to it.
Check out the quick YouTube video at the bottom of this page.
The remote is made from a VB.NET application that listens on a select COM port for commands, it also broadcasts the current playing song via the COM port to the Arduino.
You could add a Bluetooth module to this (described in our previous article here) to make it completely wireless, which would be really cool.
