Sometimes you just need to let out your emotions in a healthy way with music. This project lets you build 3D printed stomping pads to send MIDI notes with a Circuit Playground Express running CircuitPython.

The two 3D printed squares have pieces of copper foil sheet on each side. Wires are soldered to the copper foil to create a digital input circuit with the Circuit Playground Express. One side is connected to GND and the other is connected to an input pin.

The 3D printed squares connect to each other with springs with the help of some hot glue so that you can press down with purpose to send MIDI notes.

The NeoPixels on the Circuit Playground Express change color depending on which input is pressed.

This project was inspired by the Garageband and Makey Makey Stomping Pads project by Frazer Merrick.
