Design of Automobile Turn Light Control System Based on MCU

With the rapid development of the automotive industry in recent years, there have been some problems with automotive accessories, such as traditional car turn signals that do not respond in a timely manner, are incorrectly lit, and flash incorrectly, which can lead to large or small traffic accidents. In order to solve these thorny problems, this paper designs an automobile steering light control system based on AT89C52 MCU. The system is composed of LED light module, switch key control module, ultrasonic module, automatic control circuit, buzzer module, LCD display module, etc. Adding automatic mode in manual mode can prevent drivers from forgetting to turn on the lights, provide timely steering instructions for the front and rear cars, and also serve as a warning when the car is in an emergency, with intelligent steering warning and reminder function. After Proteus simulation verification, the car turn signal system can work and make the car turn signal more intelligent and reliable, making it easy to promote and use.
