Control a set of motors such as solenoids and servos with midi! Mehackit Music Machine Shield is an Arduino shield that has MIDI input and plays solenoids and servo motors based on the midi notes. Music Machine has been documented previously here. Music Machine has been used a lot in different Mehackit workshops and now with a custom PCB and robust connectors for motors Music Machine is much easier to set up and use and is more stable.
Musi Machine Shield will soon be available at mehackit webstore as a DIY kit.
