Design of Intelligent Tracking Car Based on PIC Single-chip Microcomputer

Abstract

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.
