The world of animatronics and robotics can be a lot of fun, and with a little imagination and work along with an Arduino you can really create some outstanding effects. One example of this is by Instructables member djsfantasi who has documented in detail a pair of eyes with well-executed lid motion.
By using two pairs of balls, one pair slightly larger than the other - they can be modified to fit one into the other and smoothly rotate around the smaller ball. Then with an Arduino-controlled servo the outer balls can be moved at will, and adding the motion detector adds a more fun and interactivity to the eyes. You can see this in the following video:
Perfect for an upcoming Halloween or puppet project - so visit the project Instructable to get started. And for more, we're on facebook, Google+, and twitter - so follow us for news and product updates as well.
Have you been reading about Arduino and would like to understand more so you can hack cars like the example above, but not sure where to start? Then order one of our 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! So to get started or for more information and to order, check out the product page.
