The main aim is to control industrial devices like DC motor, stepper motor through USB using laptops or computers. It mainly contains two units. One is the authors' PIC kit and the second one is computer or laptop. Through hyper terminal, they are giving inputs to their PIC kit. PIC16F877A is one of the latest products of microchip. It features all the components which upgraded micro controllers normally have. For its low price, wide range of applications, high quality and easy availability, it is an ideal solution in applications such as: control of different processes in industry, machine control device and measurement of different values.
