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。

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.
