The Servo Module is a high quality servo with the standard TinkerKit 3pin connector to be plugged in the Sensor Shield (remember that the Signal pin is ALWAYS the center pin). The best choice to add Robotics & Mechatronics to your project.
Servos are composed of an electric motor mechanically linked to a potentiometer. Arduino controls the Servo using the Servo Library. This Servo is continous, so by changing the width of the pulse you set the motor turning in a direction.
