Robotic Penny Whistle Plays 'Mary Had a Little Lamb' (UW Phys 232 final project)

This is a demo of my group's final project robotic instrument for the UW Phys 232 course (computational physics & instrumentation construction). It is a robotic penny whistle playing Mary Had a Little Lamb. It was designed, built, tested, and programmed over the course of the last weeks of the Winter 2022 quarter at the University of Washington. The goal was to learn embedded software development and mechanical design through a hands-on project analogous to developing real-world scientific instrumentation.

===== Design Info =====

An Adafruit Bluefruit CircuitPlayground orchestrates the music, communicating with a servo power board that runs 7 servos that control airflow and pitch. Air is supplied by a compressor running continuously, while balloons regulate the flow and release of air to ensure a smooth and consistent air supply. Most mechanical components are 3D printed from PLA on an Ender 3 Pro.

Very nice. I enjoyed the bass drone from the air compressor.
