Since its first design by Acorn Computers in Cambridge, UK in 1983, the ARM (Advanced RISC Machine) architecture has become a representative of low-power, high-performance processors, widely used in mobile devices, embedded systems, and the Internet of Things (IoT). The ARM architecture is centered around a reduced instruction set (RISC), efficient execution engines, and

What is Arduino? Many readers may have this question, and some might even think that the development board in their hands is Arduino. Wikipedia states, "Arduino is a single-board microcontroller and a complete set of development software. Its hardware includes a development board based on the ATMEL AVR microcontroller and various I/O boards; the software includes a standard programming language development environment and a burning program that runs on the development board."

The Arduino project originated in Italy, and the name

It is believed that friends who are interested in embedded development must have some understanding or familiarity with Arduino. For beginners, they often hear the saying, "Where is the best place to start embedded development? Arduino!" So what exactly is Arduino? Is it a new control chip? Or a new development software?

First, let's take a look at the physical image of Arduino. Below is the most common physical image of an Arduino (we will detail the classification of Arduino later):

The comparison of performance between Arduino and STM32: who is more powerful? Many electronics enthusiasts face a dilemma when deciding between Arduino and STM32, not knowing how to choose. Arduino has always been in a hot state, but does STM32 have more interfaces, stronger performance, and faster speed?

Arduino is more inclined towards creativity, it weakens the operation of
