When you first start learning about microcontrollers, you might feel excited when you successfully light up an LED or a seven-segment display using your code. This is a good thing and serves as motivation to continue learning. However, when it comes to experiments related to data communication, you may find it difficult to make progress. … Read more
In programming, data types are fundamental and important concepts, especially in embedded system development (such as microcontrollers), where various data types in C language are indispensable. Mastering these data types not only helps us allocate memory efficiently but also ensures the efficiency and correctness of the program. 1. Introduction to Basic Data Types In C … Read more
The Serial Peripheral Interface (SPI) is one of the most widely used interfaces between microcontrollers and peripheral ICs such as sensors, ADCs, DACs, shift registers, and SRAM. SPI is a synchronous, full-duplex, master-slave interface. Data from the master or slave is synchronized on the rising or falling edge of the clock. Both the master and … Read more
While my son was at school, driven by curiosity, I secretly disassembled his remote-controlled tank to see its internal structure for future modifications. The toy’s existing functions include remote control for moving forward, backward, turning in place, side movement, and firing bullets. I directly removed the wheels, and the wheel structure is indeed clever. Reverse … Read more

With the acceleration of urbanization, the issue of waste management has become increasingly prominent. Traditional trash cans not only have a single function but also cannot effectively address problems such as overflowing waste and odor diffusion. To solve these issues, this article designs an intelligent trash can management system based on the 51 microcontroller, which … Read more
➤ 01 Background In the analysis of the power switch circuit in the electronic assistant circuit[1], the internal description of the output ports of the ATmega series microcontrollers was introduced[2]. Specifically, when the port is used as an IO output, it can be equivalently represented as being pulled up to VCC through resistors of 19Ω … Read more
RFID (Radio Frequency Identification) is a non-contact automatic identification technology that uses radio frequency signals to automatically identify target objects and obtain relevant data. It is widely used in logistics, retail, transportation, healthcare, and many other fields. The following is a detailed introduction from the aspects of technical principles, components, application scenarios, and advantages and … Read more

First, let me clarify a concept,bare programming, which refers to writing programs on bare metal. Bare metal, in the microcontroller field, refers to a microcontroller control system with hardware, so don’t get it twisted. Programming on bare metal is like cultivating a wasteland; every shovel that goes in will hit hard rocks. What’s the point … Read more
