We built a voltage-to-frequency converter to create different notes output by an Arduino-controlled DAC. We then amplified the frequency signal so it could be heard on a connected speaker.
You "play" the piano by inputting different notes and durations into the Serial Monitor, which is what I am doing in the video below.
