Abstract

This system is about speed and speed show of electric motor which by stepwis. it can use with various kinds of mechanical systems extensively. According to the needs of actual conditions , Selection of the 89C52 microcontroller as the system of micro-controllers, the first 89 C52 made a more detailed presentation, and then introduced the stepper motor and the stepper motor drive and control the various ways, followed by motor speed and Measuring some, and then the next discusses in detail LED display and its interface circuit design and matrix keyboard design.
adopt the way in which the button chooses and choose the operation way that walks into electric motor which by stepwis ,The controlling system is designed by software and handware, The system adopts 89C52 as controlling processor. LED is a display system, with showing the speed of electric motor which by stepwis in real time. In addition, the system also study the reliability and technical and
