You can also measure the motor current absorption of each motor among other features. The arduino motor shield is based on the l298 which is a dual full bridge driver designed to drive inductive loads such as relays solenoids dc and stepping motorsit lets you drive two dc motors with your arduino board controlling the speed and direction of each one independently.
