本文介绍了Arduino代码库的强大功能， 推荐使用Arduino Uno等开发板，并详细说明了如何安装和使用Adafruit NeoPixel库来控制智能可寻址 LED灯带。文章还解释了如何组装电路、编写和修改函数以创建独特的灯光效果，并强调了库在简化设备通信和程序构建中的重要性。

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。
