51單片機課程設計分享，制作音樂花樣燈數組法法的仿真原理圖如下（proteus仿真工程文件可到本帖附件中下載）


單片機花樣燈源程序如下:
  1.                                            /*12Mhz晶振*/
  2. #include <reg52.h>
  3. #define uint unsigned int
  4. #define uchar unsigned char
  5. sbit key2=P3^3;//key2外部中斷1 控制花樣燈的切換速度
  6. sbit key1=P3^2;//key1外部中斷0 控制播放哪首曲子
  7. sbit voice=P3^7;//蜂鳴器定義
  8. uchar code sound[]={0xff,                 //每個音階  不同拍子的數據
