摘要
以单片机AT89C5 2为主控制器 ,控制电动小汽车的行驶方向 ,采用脉宽调制技术控制小车的行驶速度 采用红外光电开关识别小车行驶的位置和距离 。
Using Micro Controlled Unit At89C52 to control the direction of the automatic motor-driven car,and using the Pulse Width Modulation technology to control the speed of the motor.The location and distance of the car are detected by the infrared rays photoelectric detector,the running time and distance of the car are also displayed with digital model meantime.
