/*Analog InputDemonstrates analog input by reading an analog sensor on analog pin 0 andturning on and off a light emittingdiode(LED) connected to digital pin 13.The amount of time the LED will be on and off depends on the value obtainedby analogRead().The circuit:- potentiometercenter pin ...
Connect three wires to the board. The first two, red and black, connect to the two long vertical rows on the side of the breadboard to provide access to the 5 volt supply and ground. The third wire goes from digital pin 2 to one leg of the pushbutton. That same leg of the button ...
