/* 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.
