1、四花样彩灯控制器电子信息工程学院电子基础课程设计任务书I、电子基础课程设计题目：四花样彩灯控制器II、电子基础课程设计技术要求及主要元器件：彩灯一亮一灭,从左向右移动；彩灯两亮两灭,从左向右移动；四亮四灭，从左向右移动；从1～8从左到右逐次点亮，然后逐次熄灭；四种花样自动变换。主要元器件：555,74LS93,74LS74,74LS153,74LS164III、电子基础课程设计工作内容及进度安排：首先要对四花样彩灯的工作原理非常熟悉；然后根据原理设计出电路图；再者就是领电路所需的电子器件和焊接；最后就是要调试电路直至电路能正常工作。进度安排：前三天查资料和设计，其余的时间焊接。Ⅳ、主要参考

2、资料：《电子电路计算机仿真技术》《新颖电子灯光控制器》《Multisim电路仿真入门与进阶》《数字电路逻辑设计》专业名称：通信工程班级学号：学生姓名：吴武松指导教师：张华南设计时间：2007年9月13日　系(部、中心)主任：-22-四花样彩灯控制器摘要四花样彩灯控制器是利用几种芯片来控制不同数量而有规律的彩灯的亮灭。彩灯控制器的第一种花样为彩灯一亮一灭，从左向右移动；第二种花样为彩灯两亮两灭，从左向右移动；第三种花样为彩灯四亮四灭，从左向右移动；第四种花样为彩灯1到8从左到右逐次点亮，又从左到右逐次熄灭。4种花样自动变换，循环往复。电路图包括移位寄存器，计数脉冲，分频器，数据选择器等器件。

3、主要由555振荡电路产生两种不同周期的矩形脉冲，在经74LS93分频后得到四路分频信号，由74LS74﹑74LS153组成的选通电路来控制彩灯亮灭的顺序，从而出现彩灯四种花样自动切换。这次课程设计报告说明了设计的全过程，包括原理分析、电路说明、过程说明、设计方案说明、原理图说明、故障以及故障排除说明。关键词:移位寄存器计数脉冲分频器数据选择器-22-四花样彩灯控制器目录任务书·············································································································
