This article introduced programmable parallel communication interface pci chip 8255A’s experiment which can control traffic lights.

Implementation of Traffic Signal Lights Based on VHDL;

A convenience and feasible control system was designed to settle some problems on traffic signal lights against actual application.

The article puts forward the method of using sigle-chipmicrocomputer to control automatically the traffic signal lights andtime-show.

Use programming logic controller to implement the control of traffic signal light;

This paper introduces the methods to complete the control of the traffic signal light by using three different kinds of SIMATIC S7-200PLC instructions and procedures,and then briefly analyses the merits and demerits of the three methods.

This control circuit is simple,and can conveniently give the preset digits for the time switched on the red,green and yellow traffic signal lights,and have the function of digital display for reversed timing.
