"AT80C51单片机控制交通灯设计实践"

In this course design project, the focus is on using the AT80C51 microcontroller to control the operation of traffic lights. The project involves the automatic switching of three-colored LEDs under the control of the microcontroller, following a specific pattern as required. The design utilizes the basic components of a microcontroller system, three-color LEDs, and a driver circuit composed of a 74LS05 inverter. For demonstration purposes, the switching time is kept relatively short. The main objective of this project is to introduce the functionality of the microcontroller and the working mode of traffic lights. All programs and simulation diagrams have been successfully debugged in the Proteus software. The key components of this project include the AT80C51 microcontroller, control, and driver circuits. Overall, this course design project provides a hands-on learning experience for students in the field of electrical power electronics and power transmission. It showcases the practical application of microcontrollers in controlling traffic lights and highlights the importance of proper circuit design and programming. Through this project, students gain valuable insights into the operation of microcontrollers and their role in real-world applications such as traffic management systems.
