Preface: Fire monitoring and alarm system can convert physical quantities such as smoke, heat, and flames generated by combustion into electrical signals through fire detectors at the early stage of f...
Testing a battery-powered product, there is a 26K resistor between the two ends of the battery pad (no battery is soldered at this time!), what is the internal resistance of the board power supply cir...
The MOSFET driver circuit chip IR2110 has an output current of about 2A. Is this the drive current? The output voltage is 10-20V. So the output power of the tube is IU, or how to calculate it? Then th...

My colleague and I spent the day chatting in the hotel bar. We had met with several customers. We were both wondering how come these engineers we were meeting knew almost nothing about analog techn...[Details]
In the previous series, we have listed some basic knowledge of C language in Tables 1 to 3. We hope that beginners can strengthen their memory of the above tables and gradually learn to use them wh...[Details]
In the analysis of electronic circuits, static analysis (also known as DC analysis) is the basis of circuit analysis. However, it is well known that electronic components are nonlinear, so the anal...[Details]
RS-422 and RS-485 are both serial data interface standards, which were developed and published by the Electronic Industries Association (EIA). RS-422 defines a balanced communication interface with a ...[Details]
In recent years, with the rapid development of the information industry, dot matrix LED display screens have been widely used in various advertising and information display systems such as the fina...[Details]
I've been studying dot matrix recently. It looks simple, but it takes a while to master it completely! The 8*8 dot matrix hardware circuit I'm making now is like this. The row is driven by 74HC138 + t...[Details]
1 Introduction
There have been many studies on the detection and protection of power grid short circuit and line fault. The short circuit, overload and overvoltage protectors on the market have ...[Details]
Single-chip microcomputers are widely used because of their small size, powerful functions and low price. This article introduces the method of designing a micro electronic piano using the AT89C51 sin...[Details]
In today's body control module (BCM) designs, savvy engineers are moving away from electromechanical relays whenever possible. Their next step is to eliminate fuses. But is eliminating fuses a nece...[Details]
Today, the value of electronic components in cars accounts for 15-20% of the total vehicle. In the future, this proportion may be as high as 30-40% as more safety electronics, fuel consumption and ...[Details]
Describe how to meet the challenges of complexity with a modern wiring design toolset. Option codes and expressions can simulate the variables of an automotive project. A full-featured tool suite c...[Details]
The serial interface real-time clock chip DS1302 launched by Dallas Company in the United States can trickle charge the backup battery of the clock chip. Due to the main features of the chip such a...[Details]
