Overview
The Lumi-Synth has two touch sensors, one ultrasonic range-finder (HC-SR04), two neopixels, and one speaker. The touch sensors play the notes C and E flat respectively. The C note corresponds to the color pink on the neopixels and Eb corresponds to violet. The ultrasonic range finder plays the note D at a distance of 10 to 15 centimeters, and plays the note F at a distance of 17 to 22 centimeters. These ranges were added so the range finder would not continue playing at longer ranges. The synth uses CircuitPython and a Raspberry Pi Pico to store the information the circuit uses.
