Knock actvated lock

This is a lock which won't open with a key. It has a thing for rhythm and it will only open if you knock according to its setting. The lock is made up of an Arduino board, a microcontroller and other small things and it is quite effective. Of course, anybody who hears the secret knock can break into your house afterwards, but you can reprogram the lock at any time.
