About the Robot xylophone

This project turns a toy xylophone into a robot musician. Small solenoids, held over the bars by printed mounts, tap out notes under microcontroller control, and everything plugs together without soldering. The Printables page itself is brief. The full parts list, wiring and code are in the Adafruit Learn guide, and the Adafruit build video below walks through it.

Bought parts

  • A toy xylophone (a specific model is linked on the page)
