Blakeslee claimed he was not targeting anyone with his antics but had a habit of placing his waste in Pringles cans and randomly throwing them from his car as he traveled down the road.

I guess that’s… better?

Thats the issue, yeah. I haven’t manually read the pins yet, but I just found something strange.

I connected an LED to one of the column pins to see whether the MCU was sending scanning voltage, and it was. Then I put it in parallel to a row pin to see if the switches were returning that scanning voltage when pressed, and they were. Then I noticed that whenever I added the led to a row pin, the serial monitor showed keypresses for all the keys on that row, and the inverse when I removed the LED.

So, apparently, this whole time the key matrix library has been designed to work with a pull down resistor rather than reading return voltage. My whole PCB is modeled after mechanical keyboards, so it was not designed for pull down resistors. Now I must rewrite parts of the library or find one meant for a keyboard-style circuit.
