Stepper Motor (Unipolar) Control Via Parallel Port

03 Jul

I have built the above application for windows platform to control Stepper Motor (Unipolar) Via Parallel Port. The application can control the stepper motor in three different modes “Single coil excitation mode”,”Dual coil excitation mode”,and an “Energised Half Step mode”. The user have the freedom to control stepper motor step speeds,and the application is very much stable.The schematic is given below,the user can add IC ULN2003 or can use power transistors or MOSFET to control via parallel port.To get the application free,e-mail me at
