基于Stm32开发板的智能玩具小车的设计与实现

AbstractAbstract:With the development of science and technology in today's era,computer technology has alsoushered in a period of rapid development.In the embedded fied,a variety of smart devices and homefurnishings show that we are moving towards the era of the internet of things.Embedded tecnology iswidely used in all aspects of life.I want to apply embedded technology to toy cars,so that traditionaltoys can become more intelligent and interesting.The intelligent toy car takes STM32 as the core development board,and uses PWMtechnology,infrared remote control technology,intelligent tracking technology and ultrasonic obstacleavoidance technilogy.The key hardware used includes L293D chip,infrared signal receiver,ST188infrared photoelectric sensor,steering engine cloud platform and ultrasonic sensor.The car mainlyincludes driving module,infrared remote control module,intelligent tracking module and ultrasonicshaking head obstacle avoidance module.The car mainly includes driving module,infrared remotecontrol module,intelligent tracking module and ultrasonic shaking head obstacle avoidance module.The first is to control the car forward and backward by infrared remote control.The second is that thecar can follow the black track,turning and moving according to the black track.Thirdly,when the carencounters obstacles,the distance between the car and the obstacles is determined by ultrasound.andthe safe route without obstacles is found by ultrasound.Keywords:STM32,PWM technology,L293D chip,ultrasonic sensor
