51单片机操控LED七彩突变灯

自己规划的51单片机操控LED七彩突变灯

MCU:89C51,89S51,89C2051等

晶振:12MHz

电路驱动(LED衔接):

P1.0衔接蓝色LED

P1.1衔接赤色LED

P1.2衔接绿色LED (有必要运用纯绿色高亮LED,不行运用一般草绿管)

全为低电平驱动(低电平点亮),能够加三极管驱动,红、蓝、绿LED也能够交流方位

操控方法:PWM

频率:约300-700Hz(我没有核算或测量过,仅仅实验显现作用足够好)

调理级数:共600级,适当滑润

入无法下载HEX,我们能够用KEIL自己编译,或许运用记事本保存HEX代码(重命名为.HEX文件)都能够

再把.hex文件写入单片机,接好电路即可作业
