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
Previously, we introduced the process of discovering services and characteristics. Today, let’s take a look at what happens next.In the software, we click to control the light to turn it on and off. The data sent by the host is as follows:Captured dataOperation codeOperation code 0x12: write request.Write requestWriting the value 0x0001 to the attribute … Read more
Light Up an LED Continuing from the previous discussion, why should we learn to light up an LED before diving into microcontroller programming? The author believes that, first, in this experiment, we can learn how to add functionality to an engineering template; second, we can learn how to configure general-purpose pins to output high and … Read more
LCD (Liquid Crystal Display): Backlight source emits light + liquid crystal color rendering, with the backlight source now using LED lights. QD-LCD (Quantum Dot TV): The screen of a typical LCD TV uses an LED backlight that emits blue light, which is converted into red, green, and blue light through phosphors, ultimately forming white light, … Read more
