An Arduino is used to determine the servo’s current position versus the desired position, and it turns the motor accordingly with a BTS7960 motor driver.

If you are interested in building your very own full instructions on how to combine the Arduino CNC shield and Arduino code for controlling the to DC servo motors have been kindly published to the ...

[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor assembly, but with a stepper motor-like interface. By stacking some small PCBs behind the motor body, it was po… ...
