Wiring:

Connect a LED to IOA and IOB as follows:

Cathode (short leg) of LED connected to the GPIO pin.

Anode (long leg) of LED connected to one end of a resistor*.

Other end of the resistor connected to 5v.

* A 1K resistor is shown here as a 'safe' value. For maximum LED brightness, you can learn

how to calculate the optimum resistance in this guide: http://learn.adafruit.com/all-about-

leds (http://adafru.it/clH)

Compile and upload the example sketch and you should see both LEDs blinking: 1 second on

and 1 second off.
