I built an Arduino-controlled electronic xylophone.

Piezo disks > voltage > Arduino > OSC and/or MIDI > Garageband


Code

Github repos for the code:

  • New code uses Pure Data and OSC to create and/or play MIDI and doesn’t rely on a serial to MIDI converterĀ (updated June 15, 2012)
  • Old code relies on serial to MIDI converter
