Build your own Arduino-based Light-Seeking robot

Alex from Tinkerlog has designed and built a very simple yet somewhat intelligent light-seeking robot. It used two light-dependent resistors to measure light levels which are converted to values via the Arduino-compatible board. Servos that have been modified to rotate at 360 degrees drive the wheels, and the direction is a function of the light levels. You can see the robot in action below:

 

Building the robot is very easy, and would also make a simple classroom or weekend project for younger children to demonstrate the technology. Instructions and design tips can be found at Alex’s page here. To get started with your own Arduino-embedded projects – consider using the Freetronics LeoStick – one of the smallest Arduino-compatibles  on the market with onboard USB, RGB LED and piezo:
