Preface: Recently, I started to design a brushless DC motor electronic speed regulator. Referring to some information on the Internet, I chose the Atmega8A-AU microcontroller as the main control chip...[Details]

At the beginning of the Year of the Tiger, I want to sit down and write a serious article about my thoughts on the future evolution of cars. Since I am not an engineer, I can only talk about some tho...[Details]

Recently, the country's first precise, flexible and stable control system was put into operation. It is understood that the system is the first in the country to achieve rapid and continuous c...[Details]

  There are many ways to determine the windings and their beginnings and ends of a three-phase motor. For example, using a light-emitting diode is simple, easy, safe and fast. The judgment connection...[Details]

The standard 51 is 12T, which means 12 clock cycles (crystal oscillator cycle, for example, 12M, the cycle is 1/12M, unit is second), the machine does an instruction cycle, exactly 1/12M*12=1uS, comm...[Details]

background The proliferation of ultra-low power wireless sensor nodes for measurement and control, coupled with the use of new energy harvesting techniques , has made it possible to power fully au...[Details]

The method to identify the three poles of thyristor is very simple. According to the principle of PN junction, you only need to use a multimeter to measure the resistance between the three poles. T...[Details]

Technology is a key selling point for new vehicles today. In the past, consumers valued a car’s road performance more than anything else, but now they are willing to pay for the performance of in-car...[Details]

Electronic equipment refers to electronic components such as integrated circuits, transistors, and electron tubes. They generally include computers, air conditioners, refrigerators, washing machine...[Details]

In the circuit, we often encounter the problem of measuring voltage with large internal resistance. If the direct measurement method is used, the internal resistance of the voltmeter and the internal...[Details]

According to foreign media reports, the transition to a fully electrified future depends on low-cost, higher-performance and safer batteries. The use of next-generation battery chemistries such as so...[Details]

Background noise is a new auxiliary feature added in iOS 15, which aims to reduce the interference of external environmental noise. Background noise combined with the noise reduction function of head...[Details]

With the development and widespread application of computer technology, especially in the field of industrial control, computer communication is particularly important. Although serial communication g...[Details]

Avr microcontrollers, like other microcontrollers, have their own instructions and registers, specific IO port operation methods, timers, AD conversion, serial ports, PWM outputs, EEPROM, etc. In ord...[Details]

According to a Gartner survey of 451 senior technology leaders in the second quarter of 2024, 57% of chief information officers (CIOs) said they were responsible for leading their company's artif...[Details]
