Single chip is an integrated circuit chip, is a computer system with very large scale integrated circuit technology, has the control function of flexible, powerful, in the MCU application of real-time detection and automatic control system, microcontroller as a core component to use, output to input, and real-time monitoring system, to achieve automatic control. The neon lights are the citys beautician, when night fell, lights, neon lights be riotous with colour of dress took exceptionally beautiful city. Neon light of bright, beautiful, dynamic characteristics, is any electric light source is not a substitute for, to play the leading role in all kinds of new light source are emerging and competition. Therefore, how to design a transformation for the subject to neon variety has the significance of the times. Square neon lamp in this design is based on 89C51 single-chip design, display, infrared communication, the voice of the three functions. According to the characteristics of diversity square neon lights transform, designed five kinds of transformation, achieved by writing software. The design for the design of square of neon lamp has the advantages of simple structure, strong scala
