Using Stepper Motors to Play Theme Music

The latest youtube video find comes from a user who goes by cmhiekses and has developed a way to play the Mario theme song using stepper motors and a MIDI file. The sound comes entirely from the motors and the MIDI file is composed by the builder. The Arduino provides the commands that tell the stepper motors when to turn and stop. NEMA 17 stepper motors are used in the video and is powered by a 24 volt, 4 amp. This is a fun and creative new way to use stepper motors. Can’t wait to see what other projects this person comes up with.
