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. Many friends can't stand the "torture" of time and go about other things. They often forget to turn off the water, causing a lot of waste. When washing clothes, turning the timer can usually wash for up to 15 minutes. Most users don't do this process. He will stay by the washing machine. When the timer ends, he cannot time the time or rinse again in time. Sometimes he even forgets how long he has been washing, which greatly prolongs the washing time. 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.

Digital capacitance meter made with AT89C2051 microcontroller

As a simplified version of AT89C51, AT89C2051 removes P0, P2 and other ports, reducing the number of I/O ports. However, it adds a voltage comparator, so its functions are enhanced in some aspects. For example, it can be used to process analog Quantity, simple analog-to-digital conversion, etc. This article uses this function to design a digital capacitance meter, which can measure the capacity of capacitors with a capacity less than 2 microfarads. It uses a 3-and-a-half-digit digital display. The maximum display value is 1999. The reading unit is uniformly nanofarads (nf), and the measuring range is divided into In the fourth gear, the readings are multiplied by the corresponding magnification.
