Abstract:

This article describes the comprehensive experiment design of a simulative traffic light control system.The simulation system uses AT89S52 devices as the core and applying varied interrupt processing and time-sharing multiplexing function with P port to control the display of digital tubes and LED lights,thus realizing normal indication and countdown function of the traffic lights in a variety of situations.The software such as Keil C51,Proteus,Protel are used in the comprehensive experiment.The statistics data show that learners can master single chip Microcomputer programming better by doing the experiment.

Key words: comprehensive experiment;traffic light control;AT89S52
