+  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.
