I want to put my raspberry pi 2 in an old nes I found. I have been playing around with the pi in the past, but i was not satisfied with the result. I have desided to try again and this time do alot more then just monkey around with it.
The resistor value actually doesn’t matter that much for the shutdown circuit. Just about any resistor will work. I think I used 220 Ohm, but I just picked it out of a bag of random resistors. I’m using just a single resistor between the GPIO pin and ground 3.3v. Both the reset button and this simple shutdown circuit do work on the PI2, I’m using both.
