Build a simple Guitar Tuner with CircuitPython and Adafruit PyPortal! Use the touch screen to tap on tuning pegs and play music notes. The notes are pre-recorded wav audio files of guitar strings. The graphic of the head stock is a single bitmap. This uses the displayio library for CircuitPython and can be customized to make a unique sound board.

The Adafruit PyPortal and a mini oval speaker are secured to a 3D printed enclosure using M2.5 screws and standoffs. The PyPortal is mounted vertically and features a built-in holder for a speaker.
