本项目是一个采用Traffic LED模块、Arduino Uno/Nano，以及TOF10120飞行时间传感器的工业级智能停车系统。项目采用一块切边的垫子作为停车区，先测量垫子长度，再根据这个数值定义不同距离的代码，一个接一个的点亮（ON）和熄灭（OFF）这些LEDs，以帮助司机安全 ...

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。

Learning electronics? Then, chances are you already know what an Arduino is, or at the very least, you've heard of it. After all, it's among the most popular electronics platforms available in the ...

So you've already outgrown Arduino's most beginner-friendly board, the Uno, and are looking to move on to bigger, more exciting projects. In that case, the Nano family might just be what you need.
