Arduino Glockenspiel

This project used the brightly colored keys from a Fisher-Price toy I found at a thrift store. I remounted the keys on a laser-cut acrylic base and designed a striking mechanism that incorporated a 5V solenoid and cheap stepper motor. In the video the notes are struck in order, but for the final code I had the striker choose an endless, random pattern. Since the cheap stepper motor eventually misses enough steps to cause the striker to miss the keys, I added two buttons near the Arduino Nano that can be used to line it back up. While the acoustic result was underwhelming, this was still a fun way to pass a couple days while snowed in during early February of 2019.
