+/* Blink without Delay
+
+ 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.
