[Frank Herrmann] had an interesting idea to turn a geared DC motor into a servo motor ... motor driver’ interface pins hooked up to the motion controller upstream. The Arduino source for this ...

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. The result is a sizeable and capable ...

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...
