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.
