This is a quick attempt to control the positioning of a continuous rotation servo with just a potentiometer. With the first code I check the exact middle point (where the servo stops, 1500 theoretically); in the second one I take control of the servo.

DISCLAIMER: Because of the big inaccuracy of these motors, you can't express rotation in degrees and there is no angle feedback; so the positioning will be always very approximate. Any improvement or suggestions would be greatly appreciated!
