Arduino is checking, if there are new tweets from a specific Twitter-Account. If so, the "bird servo" starts to rotate and the bird-door opens. Then the two "sound servos" brings the Cuckoo Clock flutes to sing and the bird nod with his head. Simultaneously, the printer prints all new tweets.
If you have questions or just want to say "Hi", shoot me a mail.
"Tweety is a interactive
Twitter clock – build with Arduino – the
original 'cuckooo' sound and a little Printer for the output."
