Made a schematic and started laying out the pcb. I didn’t have enough pins for doing all the pins of the rotary encoder, but I read that just one and ground is enough for sensing movement, just not in any specific direction, which is all I need so its probably fine. I tried laying out the pieces for the pcb but then got tired, and I’m leaving it to tomorrow me to organize and fix. It’s a slow process while learning on the go. Also how do I put the led to light up a key from underneath? I have NO clue.
