Stepper motor music

Arduino Music Technology

Michael put some stepper motors to work playing back MIDI tracks by way of Arduino –

The data for the music is taken from a MIDI file I made. The code for interpreting the data and moving the motors was written by me over the course of a few days.

The sound you’re hearing is coming entirely from the motors. The motors are screwed into some pieces of aluminum from an old project to help them resonate. I’m taking requests for other songs to play.

Currently, the information for the song is stored on the Arduino. Plans for implementing a realtime MIDI stream are underway. Eventually I’ll be able to plug in a keyboard and play the motors as though I were playing piano.

Quite awesome. You can see video the project’s earlier version here. [via Adafruit]
