基于数字集成电路流水灯的设计

为了使造价低廉、清洁无污染的LED灯在电子产品装饰、显示屏电子广告、数码与字符显示、节能灯等领域得到广泛的应用，采用LED灯来作装饰已成为一种时尚。采用数字集成电路的控制方法，结合十进制计数器／译码电路设计了该控制系统。该系统由电源、时钟电路、计数器和译码显示电路4部分组成。能实现任意方式的流水，只要改变每路发光二极管的数目和图案，就可以实现随心所欲的流水花样。它可作为工作状态指示，具有环保、节能等特点。

Design of Water Lights Based on Digital Integrated Circuit

In order to make the low cost,clean and pollution-free LED lamps widely applied in the fields of electronic product decoration,screen display advertisement,numerical code and character display,and energy saving lamps,the decoration with the LED lamps has become a fashion.In combition with decimal system counter/decoding circuit,the control method for digital integrated circuit is employed to design the control system of water lights.This system is composed of power source,clock circuit,counter and decoding ...
