I have an Arduino Nano 33 IoT and a MacBook. Through a PS/2 connecter, I have the following wiring: Arduino PS/2 Seat Pads 9 1 Seat1 10 2 Seat2 11 3 Seat3 13 4 Seat4 15 …

[image] jcros214: This is a hardware question, but I did forget to state the pinMode: all pins relevant to the seats are set to input pinMode(pin, INPUT_PULLUP); Read this for a reference.

Why? Interrupts are seldom appropriate for reading manual switches (which is what a seatpad is, basically).

Also, since you have a PCB, I assume you must have a schematic. Please post it.
