3、具有很强的理论性与十分广泛的工程应用，本次课程设计的主要目的是掌握数字电子技术的一些基础知识，能够在一定程度上应用数电子技术的相关知识解决实际问题。此次的课程设计是十六路循环彩灯控制器，此电路由四部分组成。如下：第一部分是由555计时器组成的信号发生器，控制频率的变化；第二部分是由74HC163计数器组成的计数部分，其时钟信号由555计时器提供；第三部分是由74HC154译码器组成的，计数器输出不同的计数结果，即可控制译码器译码得到不同的输出信号，决定彩灯的循环变化。如果使得计数器的控制端输入不同的控制信号，进行不同的计数，则在输出端可见不同的彩灯循环输出。而最后一部分则主要是由十六个彩灯

4、构成的输出显示部分，显示在输入的信号不同时的输出结果，方便得出实验结果，进行此次实验设计的总结。关键词：555计时器、74HC163计数器、74HC154译码器、ＬＥＤ彩灯、控制器、原理。28summaryDigitalcircuitisaprofessionalfoundationcourses,ithasastrongtheoreticalandveryextensiveengineeringapplications,themainpurposeofthiscourseistomasterthedesignofdigitalelectronictechnologysomeoftheba
