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