01 Introduction The SMD RGB light is a three-color LED light made using SMD technology (Surface Mount Technology). Specifically, it packages one red, one green, and one blue light-emitting diode into a light module, which is then soldered onto a PCB using SMT solder paste to create a unit module. This technology improves the durability … Read more

The microcontroller is the core component of embedded systems, and circuits using microcontrollers are much more complex. However, when modifying and adding new features, circuits with microcontrollers are easier to implement, which is why electronic devices use microcontrollers. So, what are the challenges to pay attention to in the design of microcontroller circuits? 1. Selection … Read more
In September 2024, I DIYed an RGB LED volume meter using the ATMEGA328P to collect analog signals and drive the WS2812. The strip is 1 meter long with a total of 60 LEDs, super cool and super fun so it’s basically online 24 hours a day. Later, while browsing forums, many experts were talking about … Read more

Introduction A few years ago, I heard about a creative door lock project: the user holds a sensing device and waves it in a specific manner. Once the device recognizes the action, it unlocks the door. This action becomes a form of key. I broke down this project into hardware and software components. The hardware … Read more
The running light is a common electronic display effect characterized by multiple LED lights (or other light sources) lighting up and extinguishing in sequence, creating a dynamic visual effect similar to “flowing water” or “waves.” The running light experiment is simple and intuitive, making it a classic project for learning Arduino programming.1. Experiment Materials 1. … Read more
