  Analog Input

 Demonstrates analog input by reading an analog sensor on analog pin 0 and

 turning on and off a light emitting diode(LED)  connected to digital pin 13.

 The amount of time the LED will be on and off depends on

 the value obtained by analogRead(). 
 The circuit:

 * Potentiometer attached to analog input 0

 * center pin of the potentiometer to the analog pin

 * one side pin (either one) to ground

 * the other side pin to +5V

 * LED anode (long leg) attached to digital output 13

 * LED cathode (short leg) attached to ground
 * Note: because most Arduinos have a built-in LED attached

 to pin 13 on the board, the LED is optional.
