Hi, I tried my hand for the first time on a servo and my experience may be helpful to other people. Servos are controlled by the length of a pulse. This pulse is repeated ca. every 20mS. The pulse length can vary coarsly between 1 and 2 mS. The pulse length determines the rotation angle. If the servo starts up, it goes to a middle position, corresponding to a ca. 1.5 mS pulse. For shorter pulses the servo turns in one direction, for longer pulses to the other. The range is limited, mostly to +/- 90 degree, the accurate values depend on the servo, as does the min/max widths. Mine had a ran
