ARDUINO MOTOR SHIELD REV3 is based on the L298, which is a full-bridge dual driver designed to drive inductive loads such as relays, solenoids, DC, and stepper motors. It allows you to drive two DC motors with your Arduino board, controlling the speed and direction of each independently. You can also measure the motor current draw of each motor, among other features. This board is compatible with TinkerKit, which means you can quickly create projects by connecting TinkerKit modules to the board.
