Regarding the control system of the portable satellite tracker, I self-studied by searching for information online. Initially, I planned to use the Raspberry Pi for direct control, but I abandoned that idea as many foreign HAM operators use Arduino for control. Having played with the 51 microcontroller in college, I discovered a vast new world. … Read more
Temperature is a physical quantity that we often encounter and can intuitively feel, such as needing to add clothing when the weather gets cooler or blowing on food that is too hot. It is also necessary to measure temperature accurately, for example, the normal body temperature of humans is 37.5℃, and the boiling point of … Read more
We know that Google has always been a model in contributing open source code, with countless open source software projects under its umbrella. However, today we are not discussing open source software, but rather open source hardware—specifically, Arduino. Open source software is easy to understand, but similarly, open source hardware also uses one or several … Read more
The following experiment is designed to help students initially grasp how to use a microcontroller and achieve some interesting functions with basic electronic components. The microcontroller control module chosen is Arduino / Microduino / mCookie. These three products are compatible with each other and are essentially the same to use, all supported by the powerful … Read more
As the year comes to an end, it’s time to recommend some development boards. This time, I have selected a few boards priced from 9.9 to 99, all with free shipping included. For those without free shipping, the shipping cost will be included in the price. The recommended development boards are all from reputable brands, … Read more

With the advancement of semiconductor technology and the growing demand for smarter, safer, and more efficient systems, industrial robots have undergone significant transformations in recent years. At the core of this transformation is the use of advanced embedded processors that adopt a system-on-chip (SoC) architecture, integrating various components … Read more
Getting Started with Arduino: Light Up Your First LED from Scratch Have you ever been curious about those magical electronic devices? Have you ever thought about creating your own smart device? Arduino, as a low-threshold and easy-to-use open-source hardware platform, can help you easily open the door to the electronic world. I remember as a … Read more
For some time now, I have been contemplating setting up an environment to implement algorithms based on neural networks on a smaller (8-pin) microcontroller. After reviewing existing solutions, I found that none truly satisfied me. An obvious problem is that flexibility often comes at the cost of overhead. As usual, for a truly optimized solution, … Read more
The ESP32, as a powerful dual-mode Wi-Fi and Bluetooth chip, has rapidly become a star in the field of IoT development due to its rich features, low price, and strong development environment. The Arduino ESP32 core library is an important foundation for ESP32 development, providing developers with a simple and easy-to-use framework that makes it … Read more
The Emergence of Arduino Many people may have heard of Arduino before Micro:bit, or even used Arduino. Before the advent of Micro:bit, Arduino was hailed as the most suitable circuit board for maker education, as we can see that many maker product manufacturers use the Arduino UNO’s 328P chip as their main control chip. In … Read more
