Make a light-following robot with Arduino

Another entry in the Freetronics Instructables competition this week is a neat robot that can be directed by a spot of light, such as the effect from shining a torch on the floor in a dark room. This has been demonstrated by Instructables member joesinstructables whose design uses a neat two-wheeled platform and three light sensors to determine the source of light to follow.

Although it may not seem too practical, this project is an interesting platform to experiment with sensors, robotics and varying degrees of autonomy. Or just to have some fun, as shown in the following video:

For complete details, visit the robot's Instructable page. And for more, we're on facebookGoogle+, and twitter - so follow us for news and product updates as well.

 If you're looking into starting with Arduino and robotics, such as controlling a stepper motor (or DC motors) from your Arduino or compatible, check out our new HBRIDGE: DC/stepper motor shield. Based around the powerful Allegro A4954 H-bridge driver IC you can control two DC motors with complete ease, or one bipolar stepper motor. With connections for external power management, a complete beginners' guide and documentation - motor control couldn't be any easier. For more information and to order, visit the HBRIDGE: page
