摘要:Traffic light (traffic light) is a traffic sign placed at road intersections orcrossings, pedestrian crossings that serves to regulate vehicles and pedestrians.At certain times the volume of vehicles on each lane at the intersection is notbalanced so that triggers a long traffic jam. Traffic Lights circuit settings areused as programming language Assembler Language, Microcontroller AT89S52and some LEDs as light traffic. This tool can anticipate differences in thevolume of vehicles in each line because it can extend the timing of traffic lightson these pathways by using the buttons available.
