Arduino with a sensor for Homebrew VR headset

This is for the arduino nerds that use Unty as well.------- http://www.adafruit.com/products/1714 ------I had an arduino micro laying around so I orederd this thing, hoping id't be able to make it work with Unity to rotate the camera in an Oculus Rift like way. And I found out I have no idea how. I'm really new to this, so I need the code that goes onto the arduino and the code that gets applyed onto the camera(object). I know that at this point I sound like one of those guys on the forums that ask if you can help them out with a code and then it turns out they want you to make the whole game for them which is just Minecraft with guns. Not that I really need it ASAP, I just don't want for a (at tha point) 40$ device go to waste. Don't really expect for anyone to answer soon, but any help will come in handy.
