The 'Creator Kit' with the Arduino UNO open source computer platform provides a quick and easy introduction to the world of interactive electronics. A beginner's book provides the basic knowledge on 130 pages - many practical examples break up the theory. The included construction sheets include a robot that can turn its head, a fortune teller who is of course never wrong (but we can't guarantee that) and a dinosaur that checks a Twitter stream for new messages. A ping-pong game on a large LED matrix provides additional entertainment.
