Description: Automatic washing machine control system. Design AT89C51 microcontroller as the core control unit, through water level detection mechanism, motor control section, digital display, keypad, buzzer, etc. hardware design to achieve a washing machine automation of work processes. First proposed the overall design scheme, followed by a brief introduction AT89C51 chip and LED Driver IC 74LS244 devices such as the function and use, and then each module circuit works carried out a detailed analysis in order to design and gives the driver circuit and control circuit chip hardware interface circuit, draw a flow chart of the driving circuit, while Keil-UV3 environment prepared each circuit drivers and control procedures to achieve the system' s input and output control, so that the Automated washing machine works
