With one microcontroller PIC and some more components, we have made these practical and useful electronic projects. Each project has its specific microcontroller model. All of the circuits with microcontrollers have a .hex code which has to be saved in PIC in order for it to work. If you don’t know how to program microcontrollers, here is the information.
