摘要
介绍了一种基于PIC单片机的智能循迹小车的硬件和软件设计。该智能循迹小车以PIC16F877A单片机为主控芯片,采用单光束红外光电传感器RPR221作为检测元件、恒压恒流桥式驱动芯片L298N作为小车驱动芯片,使小车能按预定的轨道稳定地行驶,能正确地识别路径、避障,速度和路程的显示较准确,具有一定的抗干扰能力。
The paper introduced hardware and software design of an intelligent tracking car based on PIC single-chip microcomputer.The intelligent tracking car takes PIC16F877A single-chip microcomputer as main control chip,RPR221 single-beam infrared photoelectric sensor as detection device,and L298N constant voltage constant-current bridge driver IC for car driving chip,so that the car can run by planned pathway stably,identify path and advoid obstacle correctly,and display speed and distance accurately.It also has a certain anti-interference ability.
