PWM

Interrupts, driving a servo: a light tracker

In this tutorial we explain step by step how to generate a PWM signal (Pulse Width Modulation) using a timer driven interrupt routine. This PWM signal can for example be used to drive a servo. Besides some extra knowledge about the microcontroller you will have a working light tracker, after completing this tutorial!

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.
