Of course, below I will provide a complete example of Arduino serial communication. This example will demonstrate how to perform simple data exchange between Arduino and a computer. We will write a program that receives characters from the computer and performs different actions based on the received characters. At the same time, Arduino will also … Read more
1. Hardware Preparation You’ll need an Arduino development board (such as Arduino Uno) and several LED lights. Connect the anode (long leg) of the LED lights through a current-limiting resistor (usually a few hundred ohms, such as 220Ω, to prevent excessive current from damaging the LEDs) to the digital pins of the Arduino board (for … Read more

HeliOS is an open-source, free embedded multitasking kernel designed for various low-power embedded devices. It offers a rich, well-documented API that allows fine control over the system and access to kernel services (system calls), enabling functionalities such as task management, scheduler management, inter-process communication, memory management, and device management, all while maintaining a minimal memory … Read more
Recently, I have been quite busy with work, but I still managed to squeeze out some time to finish the matrix LED clock mentioned in my last article. I made a video to introduce this clock, which you can watch on Bilibili or YouTube. Today, I am writing another article to detail the design concept … Read more
Recommended Interconnection Methods for Phyphox and External Sensors ——Also answering a question from a certain student at a university Since I started using microcontrollers to expand the external sensor technology of Phyphox about one or two years ago, I have experienced the process of connecting Phyphox with ESP32, Arduino UNO + Bluetooth BLE, Arduino Nano … Read more
Implementing edge computing in embedded systems is becoming increasingly popular, with several platforms beginning to support it, utilizing TinyML – compact machine learning. In addition to the eighth edition of Arduino Nano 33 BLE launched by our company, ESP32, QuickLogic’s QuickFeather, and PICO are also building an ecosystem around TinyML. We will gradually launch activities … Read more
