For fun and something different - check out this robot project. With a 3D-printed body and an Arduino heart, Wex will detect your presence and move his head to watch you as you move past him (or her?). Motion detection is handled by two ultrasonic distance sensors, and its' head moves via a servo. Here it/he/she is in action:
With some imagination and the right sensors all sorts of things could be possible. Put it on wheels and it could possibly follow you around! Either way, to get started click here. And for more, we're on twitter and Google+, so follow us for news and product updates as well.
Interested in making things like Wex - but not too sure where to start? Then the best way to learn is with out 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!
