This robotic musician uses miniature solenoids to tap out melodies on a toy xylophone. The Adafruit Grand Central M4 controls each of the eight solenoids using CircuitPython, one of the fastest growing programming languages, specifically designed to simplify experimenting and learning.
This guide demonstrates how to build your own robotic xylophone rig, and how create your own melodies in CircuitPython.
- Wire strippers
- Laser cutter and acrylic (optional)
Doing some prep work ahead of time can simplify this build immensely. Trimming and setting aside the wires you'll need can save yourself confusion later on. Follow this image to find and set aside what you'll need before diving into building the circuit.
