本设计采用AT89S52单片机实现对霓虹灯的控制。系统由单片机控制部分和显示部分组成。显示部分的128个发光二极管成8行16列矩阵式分布。单片机I/O口输出的信号经三极管放大驱动二极管发光。不同的控制信号使发光二极管以不同的方式和花样显示。-This design adopts singlechip AT89S52 to control the neon light. The system is made up of the part of singlechip controller and the part of show. The part of show is 8 lines of 16 row matrix types. Signal from singlechip is enlarged by triode transistor to drive the LBD. The different control signal makes LBD to give out light with the pattern in different way.
