Using single-chip microcomputer AT89C51 to transform ordinary double-tub washing machine

Ordinary double-tub washing machines have a large number of users because of their low price and durability. However, as people's pace of life accelerates, there are many inconveniences when using this kind of washing machine to wash clothes: you need to add water before washing clothes, which takes about 2 to 3 minutes.

He cannot leave people while rinsing. Someone must be involved in the whole process. Very inconvenient. This article introduces a method of using the AT89C51 microcontroller to transform an ordinary double-tub washing machine. After the transformation, the entire process of water inlet, washing, rinsing, and drainage can be completed automatically. Multiple washing and rinsing methods can be selected, and single washing, single rinsing, and Manual function, very convenient.
