摇摇棒程序与电路设计说明
16只LED发光管作为画面每一列的显示，左右摇晃起到了扫描的作用，人眼的视觉暂留现象使得看到的是一幅完整的画面。
与LED点阵的显示有几分相仿。
硬件电路如下图（点击可放大）。
系统电源VCC为5V，下载程序和调试时一定要保证5V电压，实际使用时用3节干电池串联4.5V即可。
AT89S52单片机作为控制器，在它的P0、P2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。
P0口的上拉电阻RA1不能少。
串在LED公共端的二极管D1会产生一定的压降，用来保护LED，经实测LED点亮时两端电压为3V左右，在LED的安全承受围。
K1是画面切换开关，用于切换显示不同容；S1为水银开关。
水银开关的作用：
棒在摇动时，只能在朝某一方向摇动时显示，否则会出现镜像字或镜像画面，所以通过接一只水银开关来控制，使摇摇棒从左向右摇动时将容显示出来。
硬件制作：
使用的是直径5mm的红色高亮LED，感觉太大了些，远看效果很好但近看时字不够连贯。
建议使用直径为3mm的高亮LED，颜色可根据个人喜好选择。
水银开关里的水银珠很活跃，导致在接通时容易产生抖动，所以将水银开关斜向上放置（尖尖朝斜上方45°角），靠水银珠自身重力的作用减少抖动：
IC座里面隐藏元件，既美观又能保护元件：
