From the lesson Arduino and Servos

A continuous rotation servo does not have a potentiometer or stop inside of it, so the servo doesn’t “know” what angle or position it is on. All you can do with continuous rotation servos is control speed by PWMing the power, or control direction. If you need continous rotation and angle detection, then you’ll need to get a regular DC motor and an encoder. Try to get a motor with a built in encoder, or encoder attachment if angle is very important in your project. There are optical encoders which are cheaper, but they require a colorful disc on the wheel which adds errors.
