There's a huge variety of sensors to take advantage of with the Arduino platform, and one of these is a micro-electro-mechanical compass sensor. As expected, using this allows your Arduino project to determine in which direction it is heading, and this has been demonstrated with a simple robot by the WTH blog. Once the robot has been placed, a button is pressed to lock-in the heading and it will proceed to follow that heading, as demonstrated in the following video:
They've used a LM303DLHC compass, and it is easy to use with Arduino. It's an interesting experiment and shows what is possible with a MEM compass sensor.

If you're looking into starting with Arduino and motor control - 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.
