五、电路原理图及说明
系统电源VCC为5V，本款摇摇棒采用9V电池电源转换为5V电源供电。
STC89C52单片机作为控制器，在它的P1、P3口接有16只以共阳的方式连接的高亮度LED，由单片机输出低电平点亮。
8、9管脚外接复位电路，P2口28管脚外接字幕切换按键，40管脚接自锁开关，28、29管脚外接时钟电路。
LED显示棒PCB板
为了便于携带以及摇摆设计板材尺寸为2cm*20cm。
六、LED显示棒程序流程图
六、LED显示棒程序代码及说明
程序代码（见附表）
以线阵排列的16个led有两组十六进制代码组成。
将字幕代码分别送给P1、P3。
每个字幕有16*16点阵组成，在单片机中存储好四个字幕代码数组，如此往复在摇摇棒经过区域形成一个64*16的点阵屏。
实现显示效果。
七、LED显示棒使用说明及注意事项
1、按下电源开关，手握摇摇棒下部以适当的频率左右摇摆，线阵排列的16个LED灯所经过的区域即可出现字幕或图案。
2、按下切换键即可摇摆出另一幅字母或图案。
3、按下复位键即可从头开始显示所摇摆出的字母或图案。
4、使用完毕关闭电源开关即可。
A、系统电源VCC为5V，下载程序和调试时一定要保证5V电压。
B、本款摇摇棒16个LED灯采用共阳极连接。
