I programmed an Arduino to count and read the Encoders on a HUB-ee Wheel. I then took a MIDI Device and programmed it to produce a note according to the reading from the HUB-ee Wheel, so that as the wheel is turned, a different note in a scale is played, or the next note in a song is played. 

 

The device has 3 buttons:

Button 1 - Happy Birthday

Button 2 - Twinkle Twinkle

Button 3 – Jingle Bells

 

When no buttons are pressed, the defult setting kicks in and as the wheel is turned, the vaious notes of Scale C are played.
