Why is Arduino highly respected? What is its advantage? -part 1

If you browse the electronic production materials 5-10 years ago, you will be able to see a wide variety of microcontroller selection, various hand-welded circuit boards, complicated flying lines, and various MCU-based electronics in recent years. Production, it is unified, many electronic DIY works of different fields and different functions, most of which use the same control module as the core - Arduino. So what exactly is Arduino? Is it a new control chip or a new development software? What advantages does it have, and it can almost unify the electronic DIY world in just a few years?

The most common kind of Arduino object has been distinguished according to the function, which you can purchase on some online platforms, like the arduino starter kit. I believe that a user who has a little understanding of the development of the MCU must have found that, isn’t this a control board with the minimum system of ATmega MCU as the core? Yes, Arduino is a single-chip control board with ATmega microcontroller as the control core. In addition to the ATmega328 minimum system circuit, the board also includes a voltage regulator circuit, a USB to serial port circuit, some LEDs for indication, and some expansion circuit sockets. Why is it possible to be the world's smallest system with only one microcontroller? It seems that Arduino has no special advantage, so why is Arduino getting such a hot pursuit?

To answer this question, we must first review the development of Arduino. In 2005, Massimo Banzi, a teacher at a high-tech design school in the Italian town of Ivrea, in order to provide students with a cheap and good using microcontroller platform, the original Arduino control panel was designed in collaboration with David CuarTIelles, a Spanish chip engineer who was a visiting scholar at the school. Then Arduino began to quickly become popular in Europe, and gradually spread the spring breeze around the world.
