The light source detecter makes used of the variation of the separated voltage by the resistivity of photosensitive resistance input to the singlechip. If the voltage higher than a worth, the singlechip will regard it as high voltage state, it means that the light source has been detected. Otherwise the low voltage state means the light source has not been detected.

光源探测是利用光敏电阻阻值分压的变化向单片机输入，电压大于某值时，单片机认为是高电平，即表示该路探测器感应到光源，否则为低电平，即表示探测器没有感应到光源，如此即可由两路信号判断光源的方向。
