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。 为了安全与隔离，LED 灯带不直接由 Arduino 供电，而是： 灯带的 正极( ...

导语：昨天介绍了如何用柠檬做个LED灯，如果你觉得那个too simple，不防尝试用Arduino来控制RGB LED灯吧。 昨天介绍了如何用柠檬做个LED灯，如果你觉得那个too simple，不防尝试用Arduino来控制RGB LED灯吧。 这一步比较随意，将LED灯接到面包板任何地方都行，不过灯的 ...
