Interrupts, driving a servo: a light tracker

In this tutorial we explain step by step how to build a small robot that drives in the direction of the light. For this the robot uses a servo and two light sensors. The same principle could be used to always perfectly align solar panels in order to maximize their performance.

Building a light-eating robot

Everyone dreams of building their own robot. With the Dwengo board, some Lego™ and this tutorial, this becomes easy. Step by step we'll show you how to build a robot that can autonomously drive towards the light. Using this tutorial, a basic explanation on some different kinds of sensors and your own imagination, you can extend your robot into a line-follower or even an advanced sumobot.
