Design of fully automatic washing machine based on 51 microcontroller
(Simulation + Program + Schematic + Design Report)
Function introduction
Specific functions:
1. Set 4 washing modes: “standard”, “economy”, “individual” and “drainage”.
2. Divided into strong washing and weak washing (motor speed).
3. The process is divided into “water intake”, “rinsing”, “washing” and “dehydration”.
4. Buttons control start, pause, and continue.
5. Different washing modes are divided into different washing processes.
Detailed process
Components used:
Microcontroller: STC89C51;
(Note: The microcontroller is universal, whether it is 51 or 52, whether it is stc or at, the pin functions are the same. The program is also the same.)

Key function requirements
(1) Use the “K1” key to step by step change the four modes of “standard, economical, independent, and drainage” and execute the corresponding program. The corresponding indicator light is on.
(2) Use the “K2” key to step by step change the two modes of “strong washing and weak washing”, execute the corresponding program, and the corresponding indicator light will light up.
(3) Use the “K3” key to control the running, pausing and alarm functions of the washing machine.
Mode and function selection requirements
(1) Standard method: water inlet->washing->drainage->water inlet->rinse->drainage->water inlet->rinse->drainage->dehydration.
(2) Economical method: water inlet -> washing -> drainage -> water inlet -> rinsing -> drainage -> dehydration.
(3) Separate mode: water inlet -> washing.
(4) Drainage method: drainage -> dehydration.
