Cuckoo Clock
Cuckoo Clock
Assignment: Put the door and bird together so that the bird sticks its head out when the door opens and goes back as the door closes. Once you get the mechanics to work, try to control it from Arduino.

/* Cuckoo Routine
* Theory and Practice of Tangible User Interfaces
* 28 October 2011
* Martin, Sebastian, Hilfi, Margaret, and Justin
*
* Make cuckoo bird come out to indicate what "time" it is. The bird only comes out if time changes.
