Digital Input – Output to Processing Controlling the Screen with a Button 1. Controlling an LED with Push A push‐button will open (or close) a circuit when pressed. Its circuit is shown Button below. The black wire goes to ground, the yellow to the pin (2 for this case), and the 10 K resistor connects to 5 V. If you connect the 10 K resistor to ground and the black wire to 5 V you inverse the state of the push button. 2
