In this video, I show you how I modified my XYZ microscope stage controller circuit to make it entirely self-sufficient. Previously, the microcontroller was not powered by an external power supply, but it was powered by a USB cable and a mobile charger. However, this is no longer the case. I added an extra voltage regulator to the circuit and now there's no need for another external cable connection to power the microcontroller. Also, although the microcontroller is externally powered, thanks to a simple modification, it can stay powered while it is connected to a computer via USB.
