The cumulative counter of the packaging line made using a single-chip microcomputer has the function of saving the count value after shutdown and controlling the start/stop of the conveyor belt motor. The circuit is simple, reliable and practical.
In industrial control, it is often necessary to count and measure products to achieve automatic control of equipment. This article introduces a method of making a counter that can set the count value arbitrarily within the display range. Moreover, the current count value, set value, and magnification value will not be lost when power is turned off. It is compatible with a variety of input signals and has a magnification accuracy of up to 5 digits. It is easy to use, stable and reliable, and can be widely used in machine tools, rubber, printing, pharmaceuticals, and cables. , textile, complete sets of control equipment and other industries.
The circuit in this design can control the automatic operation of the water pump motor according to the water level in the water tank and the set time. It has been used for more than a year and has excellent anti-interference and stability. Now I will introduce it to peers and microcontroller enthusiasts. The specific circuit is divided into four parts: microcontroller circuit, power supply circuit, water tank circuit and motor control main circuit.
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.

Based on the blood pressure monitor design of MSP430F149, the project file may not be opened. Please create the project by yourself and add several other *.c *.h files at a time according to the file names contained in the main file. There may be some problems with the final result, but the basic idea is correct. If you modify it a little, you should get the correct result.
It must be 10 points. This is the result of my three months. It is a program for competition. You can download it. If you don’t understand, you can ask.
