Using MakeCode and Circuit Playground Express you can make interactive projects using lights and sound. In this project we'll build a custom PCB for the CPX and use capacitive touch to make a playable mini synth instrument.
3D Printing and CNC Milling
This project uses both processes to create a custom synthesizer that is simple to use. This guide will cover basics of using the Bantam Tools Desktop CNC and Eagle CAD to create PCB shields for the Circuit Playground Express.
