Parallel Port Used to Control Stepper Motor

Featured in this project is the control of a stepper motor with its speed, direction, and step size by sending some signals through the parallel port.

The project provides better understanding and control of the master motor by building this versatile stepper motor control. It also illustrates how a PC and external devices interact with each other using the PC interface via parallel port. The construction and assembly requires some knowledge of either Visual basic or C, accessing parallel port, and a little understanding of electronics.

The code was programmed in Microsoft Excel VB editor which can easily make changes, edit the code, and simply run it. Microsoft Excel VB editor is very easy to understand and edit than VB itself. The whole project was documented in Word format where the construction was explained in a very systematic manner.

An external power supply can be used to run the device while using the stepper motor. Various stepper motors can be used to build a robotic arm as well as several applications such as precisely controlling the rotation and position of digital camera, fitting a webcam, or like building a car robot.
