Stepper Motor Control Based on AT89S51 Microcontroller

Along with the application of computer and microelectronic technology in industrial production, the use of computer technology and microelectronic technology to control the stepping motor has gradually become a new technology. Stepper motor control system is designed based on AT89S51, including the hardware circuit design and software design. Keyboard input signal is used to control the stepper motor rotation direction and speed. The rotation direction is displayed by LED. The design has high reliability and strong stability, which can be applied to the field of disk drive, robots and automation instrument.
