Microcontroller as a core component to use. The modern age is an era of automation, traffic light control and many other sectors of the equipment are closely related with the computer. A good traffic control system, will give road congestion, illegal control give technical innovation, along with the large scale integrated circuit and the rapid development of computer technology, as well as a technology in the control of the application. Equipment had very great progress, is the modern science and technology development direction. This design uses a single chip system and an external device, is used in single-chip assembly language to write procedures. The single chip microcomputer based on AT89S52, have good circuit diagram, program design using the software is written in KEIL4, using USB procedures to generate 16 hex file downloaded to a single-chip inside and then run. This article mainly from the application of SCM to realize the crossroads traffic lights management, to control the vehicle past the normal traffic.
