Push the handle of the slide switch to the pin connected with pin 12 which is high level, we can light up the led at pin 6 by programming. Arduinoprojects101.com */ void setup () { pinmode (2, input); Open arduino ide, select the right board and port. Const int but1 = 13; We will also change or rearrange the leds.
