This essentially turns the servo into a geared DC motor with position control disabled. The below circuit diagram shows how a arduino servo motor control can be done using a potentiometer. Connect the ...

In Arduino we will be operating the motor in 4-step sequence so the stride angle will be 11.25° since it is 5.625°(given in datasheet) for 8 step sequence it will be 11.25° (5.625*2=11.25). The ...
