此次是用光敏做的寻光传感器，总共5路，mega128程序-This is done to find photosensitive optical sensor, a total of 5 Road, mega128 program

做智能车时的自动循光程序，小车的光线探头可以根据检测到的光源方位，自动调整小车前进方向-Do the smart car light auto follow procedures, car light sensor can detect the light source position, automatically adjusts the car forward direction

控制步进电机指向光最强的一处光敏电阻，可以用作坦克打靶-Stepper motor control point of a photosensitive optical strongest resistance, can be used as target practice tanks
