Okay, so this is the kind of stuff I want to do with my recently acquired arduino kit!
I think instead of using the knocks, a grid of magnetic sensors would be much more appropriate. What you do is carry a small magnet around on your keychain (if you don't already) and wave it at the door in a given pattern right,down,left,right and the door magically opens
Now that could take care of giving temporary access to premises to whomever you wish.

Very nice! I've picked up an Arduino of my own, but haven't gotten around to doing anything that cool with it.
