I hope this is the right section, reading controller data could be considered a form of sensor that reads what the person's fingers are doing.
I want to use a PS2 controller (with PSX support) but I am having a hard time deciding which of the library is the better one to use. Can you suggest one? I intent to use it with ATMega328 in 3.3v mode since the controllers are designed to work at 3.3v anyway.
