Today, I’ve been working on creating a piano with circuit python. I have most of my C scale programmed on the board, and I’m planning to add more scales to it.
How does it work? If you touch a certain part of the board, it produces a pitched sound. One part of the board produces a different pitch than the other. How it does it is the frequency number. For example, a C note is 261.63 Hz.
