Click the blue text to follow us! A sensor (English name: transducer/sensor) is a detection device that can sense the information being measured and can convert the sensed information into electrical signals or other desired forms of information output according to certain rules, to meet the requirements of information transmission, processing, storage, display, recording, and … Read more
Sensors are devices designed based on the physical, chemical, and biological properties and laws of materials. There are various types, and in the measurement and control field, a sensor designed based on a certain principle can simultaneously measure multiple non-electrical quantities. Sometimes, a single non-electrical quantity can be measured by various sensors based on different … Read more
Chips are one of the greatest inventions of our time. Without the advent of chips, it is hard to imagine what today’s electronic era would look like.Everyone operates a “computer” the size of a house, carrying a huge “phone” while talking to distant friends, albeit with poor sound quality.It is precisely because of the invention … Read more

The buzzer is a common device, which can be divided into passive and active types. Choose different types of buzzers based on project requirements. In a recent project, we used an active buzzer. As usual, we first designed the circuit board and then proceeded to programming. The schematic in the project is as follows: If … Read more
For embedded systems, if there is no RTOS running, the main function main() in program development needs to use some mechanism to keep running happily forever, it has no endpoint. If you want to exit from the main function, what happens specifically is determined by the C language compiler used. 1. Introduction to the Problem … Read more
In microcontroller programming, many engineers need to operate on registers, among which the reset operation is particularly common. According to the reset method, resetting can be divided into writing 1 for reset and writing 0 for reset. So, is there a difference? Can they be used interchangeably? 1. Operation Method Writing 1 for reset: In … Read more
The AT89C51 is one of the most widely used 8051 microcontrollers, and importantly, it has the feature of being reprogrammable (FLASH). Generally, it can be rewritten 1000 times, providing a low-cost platform for beginners to experiment. To meet the hands-on needs of microcontroller enthusiasts, I spent half a month designing and successfully creating a simple … Read more
