If projects like this interest you, however you’re not sure about using servos or Arduino in general – don’t panic! Check out our new Experimenter’s Kit for Arduino:

The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don’t leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words – this is everything you need to get started for a fun range of electronics and Arduino related projects!
