Analog Synthesizer

Veeryan Bhatia, Artem Shumay, Sebastian Echeverria

This project synthesizes a waveform of variable frequency and uses a Class D amplifier to play it through a speaker. The board is powered by a Raspberry Pi Pico and communicates with the amplifier over SPI. The board takes in 8 digital signals in the form of buttons and switches, and 1 analog one in the form of a rotary potentiometer.
