Adapted from the Ruiz Brothers original Circuit Playground Case Project
A pitch pipe made with the Circuit Playground Express!
This project uses Adafruit's Circuit Playground Express as a pitch pipe
Many vocalists and choirs use chromatic pitch pipes, which are essentially chromatic harmonicas, to find their starting pitch.
Now it's time to make one with the Circuit Playground Express, along with a fun 3D printed case!
