摘　　要：随着时代的推移,许多产品在保证其性能的前提下也开始变得越来越美观。其中LED流水灯的应用也越来越广泛起来。利用单片机进行控制使得LED产生流水效果由于成本低廉,操作便捷而便备受青睐。本文选择使用C51单片机利用C语言编程控制LED小灯的闪烁,利用单片机P0-P3口输出的高低电平差异使得不同的小灯发生不同的明暗变化从而产生流水的效果。并引入循环语句和分值语句完成流水灯样式的循环和自动切换。With the passage of time,many products have started to become more and more beautiful while ensuring their performance.Among them,the application of LED flowing lights is also becoming more and more widespread.The use of microcontrollers to control LEDs to produce the effect of running water is very popular because of the low cost and easy operation.In this paper,we choose to use C51 microcontroller to control the flashing of LED lights using C language programming,and use the difference between the high and low levels of the output of the P0-P3 ports of the microcontroller to make different lights change to produce the effect of flowing water.It also introduces the loop statement and fractional statement to complete the cycle and automatic switching of the flowing light style.
