不太懂，总共有四个光敏管，是把哪个光敏管放在焦点上？
四个都放在焦点上,四个管的输出相同,当光线偏移的时候,焦点就会移动,四个管输出就会有变化,你拿个放大镜来试试就懂了. 为什么我吧你的代码复制到 arduino IDEshang直接就是这样显示的：
sketch_jul21a:1: error: 'Servo' does not name a type
sketch_jul21a:2: error: 'Servo' does not name a type
sketch_jul21a.cpp: In function 'void detection()':

时间长了不会把光敏烧坏吧 cyq456 发表于 2013-7-22 16:35 static/image/common/back.gif

四个光敏的面积还是挺大的,应该不会烧吧,不过还真要试试才知道.
