So here's what I'm doing: I wanted to create a small button panel for a game so I can learn about the process. I decided on eight buttons (arranged into a matrix), two toggle switches, and two rotary encoders. I only plan on pushing one button at a time, which is why I didn't install those diodes to stop ghosting.
Perhaps you all can help me with several questions I have about the programming side of things:
How do I define what the rotaries and switches are plugged into? And how to I tell the board what to do when each button is pressed? I've been looking at some tutorials and don't entirely understand. Below are pictures and the main video I've been referring to.
