In this video we will learn how to turn any DC motor into a stand-alone servo motor with a lot of features. Unlike regular servos that have limited motion of 180 or 270 degrees, this one has unlimited range of 360 degrees and in addition to that we have the ability to adjust the range of the rotation to whatever value we need. We can also set a custom center point, we can adjust the responsiveness, it has continuous rotation mode and it can be controlled through an analog input, digital input from a RC receiver and using the serial monitor from our PC.
