摘要
设计一种基于单片机控制的智能小车。应用STC89C51单片机作为智能小车的核心控制器件,通过分析H桥路的工作原理,以LM393为电机驱动芯片,结合光敏电阻、光电传感器、红外传感器和超声波传感器,控制智能小车在赛道上按照预定轨迹完成前进,后退,左转和右转,并能有效避障,实现自动寻迹。
This paper designs an intelligent car controlled by a single chip computer.The STC89C51 single chip microcomputer is used as the core control device of the smart car.By analyzing the working principle of the H-bridge,LM393 is used as the motor drive chip,combining the photoresistor,photoelectric sensor,infrared sensor and ultrasonic sensor,the smart car is controlled to complete the forward,backward,left and right turns on the track according to the predetermined track,and can effectively avoid obstacles to achieve automatic tracking.
