Abstract: This article introduces a new design method for a LED color light control system, using the AT-89C51 microcontroller as the main control core, combined with minimal auxiliary hardware circuits such as buttons and displays. The system controls LED color lights through software, featuring a compact size, fewer hardware components, a simple circuit structure, and … Read more
I previously open-sourced the ESP32C3WROOM board, and today I’m open-sourcing the ESP32C3FH4. You can directly obtain the engineering files at the Lichuang Open Source Square. https://oshwhub.com/zctnb/works Actually, the chips are the same, but the ESP32C3WROOM is a module, while the ESP32C3FH4 is a chip that integrates 4MB of flash. Let me explain for those who … Read more
Layered Thinking Layered thinking is not a mysterious concept; in fact, many engineers working on projects are already using it. I’ve seen many posts that do not mention this concept, yet a layered structure is indeed very useful, and once understood, it can lead to a moment of clarity. If I don’t understand how to … Read more
