课程设计论文 题 目： 基于51单片机的流水灯 院 （系）： 信息与通信学院 专 业： 电子信息工程 学生姓名： 张翠萍 学 号： 1000220407 指导教师： 王岩红 职 称： 副教授 2012年 12 月16摘 要 单片机控制系统能够取代以前利用复杂电子线路或者数字电路构成的控制系统，可以软件控制来实现，并能够实现智能化。 本次课程设计中我主要采用STC89C51RC单片机作为控制主体，通过对编写程序代码实现用P0口来控制LED灯来显示出流水灯的效果。设计中辅以简单的设备和必要的电路，设计了一款流水灯最终达到预期的目的。 关键字： STC89C51RC；流水灯； LED灯 Abstract Single-chip microcomputer control system can be replaced by complex electronic circuit or before digital circuit consists of the control system,Can control to realize software, and be able to realize intelligent. This course design I mainly use the STC89C51RC microcontroller as the control subjects, through to write the program code realization P0 mouth with to control LED lamp to display.The effect of flowing water light out. Design with simple equipment and the necessary circuit, design a kind of flowing water light finally achieved.The purpose of the expected.
