I just uploaded a new video tutorial on how to use the Grove dual H-Bridge module with the DynamixShield and an Arduino Due to control DC motors.
The DynamixShield is a product I am building that works with the Due to give you the ability to control Dynamixel smart servos, and it has a ton of Grove and RobotGeek connectors. Grove and RobotGeek are frameworks for robotics that allow you to purchase commercial modules and plug them in with a single cable. In this video I show how to use a Grove module to control DC and stepper motors.
If you like the DynamixShield and would like to have one, then please support my Kickstarter campaign so I can get them produced and made available.Here is a link to the campaign:
