Choose Arduino Fio as your board type in the "Tools" menu (the AirBoard is derived from the original Fio)

Arduino COM Port Selection

Choose the appropriate COM port (check Windows Device Manager or Linux /dev directory).

Import AirBoard and Sensor Libraries into the Arduino IDE

You will need to download/check out the code hosted here. Copy the directory tree for each library into your Arduino Library folder (typically "My Documents\Arduino\Libraries" on Windows).
