This project show you how to build Unipolar Stepper Motor driver for high current. The driver able to handle up to 20A. The main component in this driver is L297. While the driver circuit is more or less taken from the L297 datasheet. More features from the project are : Handles a maximum of [...]
This project enables you to drive two unipolar stepper motor or eight electric light bulb or DC motors. There are eight DC power switch you can open or close through PC parallel port. For safety reason, digital interface to PC uses optocouplers. You can connect up to six circuits to a single LPT, driving [...]
