当环境光线变亮时，又自动关闭灯带。 连接 Arduino ↔ LDR 分压 ↔ 继电器模块 ↔ 12V 灯带。 热熔胶枪（可选） 用于固定 LDR 位置或整理线材，提升结构可靠性。 A0 点的电压随光照变化而变化，Arduino 通过 analogRead(A0) 读到 0–1023 之间的数值，即可反映当前亮度。

In this project I did a Christmas jumper with rgb LEDs, this can also be a creative clothing project or whatever you want, it ...

I’ve seen a lot of Pixel LED projects and know every maker does things differently. I wanted to show you what I am doing for my Pixel LEDs. This post will give you an Arduino Pixel LED Controller ...

I have spent at least an hour almost every day since the 80’s advancing my knowledge in electronics. Recently I brushed up my knowledge on LED fading secrets and attained something pleasant. Now, I’d ...

First of all, you need to download the Arduino IDE on your computer from its official site so that you can write the code and upload it to the Arduino UNO board. Now follow the below steps to do the ...

When you read “Arduino wristwatch”, you fall into the trap of envisioning an Arduino UNO clumsily strapped to someone’s wrist. [Marijo Blažević’s] creation is much more polished than that. A round ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
