2、具中去，现以该课题为例进行分析与设计可编程的彩灯控制的电路很多，构成方式和采用的集成片种类、数目更是五花八门，而且有专门的可编程彩灯控制电路。绝大多数的彩灯控制电路都是数字电路来实现，例如：用中规模集成电路实现的彩灯控制器主要用计时器、译码器、分配器和移位寄存器等集成。本次设计的可编程彩灯控制电路就是用计数器和译码器等来实现的。关键词：计数器；555定时器；发光二极管1.AbstractInrecentyears,duetotherapiddevelopmentcircuits,makedigitallogiccircuitdesignundergoneafundamentalchange.I
