Build the circuit according to the following diagram.
• Connect one of the pins on the left side of the button to pin14, which is connected to a pull-down resistor and a
0.1uF (104) capacitor (to eliminate jitter and output a stable level when the button is working).
• Connect the other end of the resistor and capacitor to GND, and one of the pins on the right side of the button to
5V.
