Washing machine control system designAbstract:With the growth of society and economy.automatic washing machines have begun to slowly replace the traditional manual laundry!The advent of the first washing machine in the 19th century has brought tremendousbenefits to mankind.It seems that in the recent decades,due to the rapid development of computer networks in various fields of society,the use of single-chip microcomputers has also continued to increase.At the same time,it has also mobilized the new momentum of traditional control and detection.In the design and development of application microcontrollersystems,single-chip microcomputers are often used as the core components.Therefore,it is not enough to grasp theknowledge of SCM in one piece.We should also thoroughly understand the specific application object characteristics of the SCM,and combine the detailed hardware structure and software combination to further improve the entire system.The design of the washing machine control system is based on 51 single-chip microcomputer,through the combination of 51 single-chip microcomputer and peripheral circuit,controlling the time of digital display,LED lamp water inlet,water outlet simulation,DC motor rotation,buzzer vocal simulation to give voice prompts.Excellent hardware is important,but if there is no software to drive,the hardware is a shell without a soul,a vase.Whether it is in the computer or washing machine system designed this time,software optimization can make the overall effect more ideal.The main idea of Bbthis paper is to compile and implement fiunctional modules through a combination of hardware and software.Keywords:MCU,DC motor,buzzer,number keys,LED indicator,digital tube
