This report introduced the Microcomputer Principle and Interface Technology, one- traffic light controller design and realization of the simulation at the crossroads of major traffic lights, traffic lights also introduced the principle of the controller and the circuit wiring, the main use The chip has a programmable communications interface chip parallel 8255A. Used in the design of the programming language is assembly language, delay is used in software delay (that is, through compilation of instructions). Preparation of the design used by the Instrument Science and Technology Garden have produced TD-PIT+ a set of experimental system. In the laboratory testing will be compiled after the adoption of procedures designed to see the results.
