The Motor Shield Kit, from the Maker Shed, is great for adding motors to your next Arduino project. Connect bi-directional motors, stepper motors, and servos in various combinations. Four independent H-Bridges make it perfect for robotics! Head over to Make: Projects and check out Nick Brenn’s Bot build for a great example using an Arduino, a Motor Shield, and a 4WD Platform!
