The main aim of the project is to control the stepper motor using PC. Stepper motor can move either clockwise or anticlockwise through the set of commands given from the hyper terminal of PC.   Stepper motors are mainly used in Robotics to control the directions of Robot. This project describes a new economical solution of robot control systems. The presented robot control system can be used for different sophisticated applications.   The main controlling device of the whole system is a microcontroller. USBTTL and stepper motor are interfaced to Microcontroller. The commands given from PC hyper terminal software will be sent to the microcontroller using serial communication through a  HyperTerminal software from PC used TTL logics and vice versa. The Microcontroller process the data received from PC and acts accordingly on the stepper motor. To perform the task, Microcontroller is loaded with an intelligent program written in embedded ‘C’ language.
