+
+ Turns on and off a light emitting diode(LED) connected to a digital
  pin, without using the delay() function.  This means that other code
  can run at the same time without being interrupted by the LED code.

+
  The circuit:
  * LED attached from pin 13 to ground.
  * Note: on most Arduinos, there is already an LED on the board
  that's attached to pin 13, so no hardware is needed for this example.
