* Writes a value to the servo, controlling the shaft accordingly. On a standard servo, this will set the angle of the shaft (in degrees), moving the shaft to that orientation. On a continuous rotation servo, this will set the speed of the servo (with ``0`` being full-speed in one direction, ``180`` being full speed in the other, and a value near ``90`` being no movement).
