Stepper Motor Control Using PC

The personal computer, which is used for various software related tasks, can act as a good monitoring and controlling system for the control of electrical and electronic appliances. This type of control of appliances using a PC is one of the major parts of the home automation system, which helps to control the home electricity usage for better energy management. We would like to control the stepper motor, as an example for controlling the electronic appliances through PC, in our paper. In this paper, a software program will be developed to access the serial port of a computer so that one can transfer data between the system and the external hardware. A stepper motor driver IC, a controller will be interfaced with the serial port of the computer. Based on the code written and the user input, the switches in the IC turn on and apply the signal to the stepper motor. This method of Stepper motor control is cheap and useful in robotic applications. Initially the technique of controlling the electrical and electronic appliances using PC will be discussed and using this technique, motion control of Stepper motor will be implemented in the paper.
