#1楼主：迎奥运，给小朋友的

因做过好几种POV，对做摇摇棒也就没有什么问题了，没有画电路图就开始了，从开工到完工，也就两个小时左右。

看，效果还不错吧？

全手工洞洞板打造

这是水银开关的特写，注意这个开关的放置方式（想想看为什么是歪着的？）

本来电路很简单，为照顾刚学51的朋友，还是画了个原理图

C51源程序如下：

#include <reg52.h>

char KY;

unsigned char code GB_16[] =       
{
      0x00,0x00,0x00,0x00,0x1F,0xE0,0x0F,0xC0, //中
      0x08,0x40,0x08,0x40,0x08,0x40,0xFF,0xFF,
      0x7F,0xFE,0x08,0x40,0x08,0x40,0x08,0x40,
      0x0F,0xE0,0x1F,0xC0,0x08,0x00,0x00,0x00,

      0x00,0x00,0x00,0x00,0xFF,0xFF,0x7F,0xFE, //国
      0x40,0x0A,0x49,0x0A,0x49,0x0A,0x4F,0xFA,
      0x4F,0xFA,0x49,0xCA,0x5B,0x7A,0x49,0x2A,
      0x40,0x0A,0x7F,0xFF,0xFF,0xFE,0x40,0x00,

      0x00,0x00,0x08,0x01,0x08,0x0E,0xFF,0xFC, //加
      0x7F,0xF0,0x08,0x04,0x08,0x02,0x0F,0xFF,
      0x1F,0xFE,0x08,0x00,0x3F,0xFE,0x1F,0xFC,
      0x10,0x08,0x10,0x08,0x1F,0xFE,0x3F,0xFC,

      0x00,0x00,0x08,0x20,0x87,0x1E,0x72,0x7F, //油
      0x31,0xC6,0x06,0x00,0x00,0x00,0x1F,0xFF,
      0x0F,0xFE,0x08,0x42,0xFF,0xFE,0x7F,0xFE,
      0x08,0x42,0x0F,0xFF,0x1F,0xFE,0x08,0x00
};

{
unsigned int x;
for(x=0; x<=N;x++);
}

void intersvr0(void) interrupt 0 using 1
{

if(KY==0){

for(i=0;i<64;i++){
   P2=~GB_16[i*2];
   P0=~GB_16[i*2+1];
   DelayUs(80);
   P2=0xff;P0=0xff;
   }
   }
}

/*演示主程序*/

}
