All right your circuit is now finished. You can start writing code. Turn on the LED when button is pressed, turn it off otherwise What we want to achieve is simple: when the button is not pressed, the LED is off. And when we press the button the LED should be on. The code #defin...

A digital pin (pin 8 in our circuit) to the other end of the GND leg. Connecting the resistor to GND sets the push-button’s state to LOW (0). The resistor is known as a pull-down resistor. On the other hand, it would be a pull-up resistor if it was connected to the power ...
