Toy piano converted into a self-playing instrument

Arduino TeamAugust 14th, 2019

Upon obtaining a small toy piano, Måns Jonasson went to work “Arduinoizing” it with 30 solenoids to hammer out tunes. 

A MIDI shield is used to pipe commands from a computer to the Arduino Mega that’s used for control, and after experimenting with discreet wiring and electronics for each of the solenoids, he switched to motor shields as outlined here to simplify the setup. This, along with a new version of the solenoid holders he designed, cleaned up the build nicely, allowing it to play a plinky version of the Super Mario Bros. theme song.

Be sure to check out the Mario themed auto-concert in the video below, plus a video outline of its construction, below.
