Single chip microcontroller is favored by many electronic system designers for its smallness, full function, low price and easy application. Its pretty fit for realtime control as a core in industrial controller, intelligent apparatus, intelligent interface, intelligent weapon device, universal measure control unit, etc. This article designs a fullautomatic washing machine control system with AT89S51 as core. This system realizes whole working course of fullautomatic washing machine, including four parts: user parameter input, wash, dehydrate and ending music play. Hardware system is made up of three modules: power supply circuit, digital control circuit and machine control circuit. Power supply circuit provides steady DC 5V voltage for digital control circuit and AC 220V for motor. Digital control circuit takes charge of controlling the working course. It consists of AT89S51, doublefigured moncathoded numeral display, buttons, buzzer, LED. Machine control circuit realizes the functions of water level detect, motor driven, water import and export, it consists of water level detector, motor, transmission system ponents and penstocks. After downloading the program to AT89S51, this circuit can realize basic functions of fullautomatic washing machine. It seems hard for this control system to pare with perfect ones in the electrical appliance market, but it has certain practicability.
