/* 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.

// constants won't change. Used here to set pin numbers:
