LED摇摇棒很好地利用了人眼的视觉暂留特性。下图是基于51单片机控制、32只高亮度LED发光LED构成的摇摇棒,配合手的左右摇晃就可呈现一幅完整的画面,可以显示字符、图片等。演示效果见自制LED摇摇棒效果展示图
黑暗条件下拍摄的效果图片:
基本原理与硬件电路设计:
32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) 由于上传不上去我画的图,所以就截图分享一下!
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者镜像画面,所以采用接一支水银开关来进行控制,使摇摇棒在摇动过程时将内容显示出来。
硬件制作:包含单片机、PCB板、32个高亮蓝光LED、电池盒、震动开关、轻触按键、3pin插针(预留的程序下载接口)
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:
软件设计:
/****************************************************************************************
/*描 述: 摇摇棒程序,通过滚珠开关检测周期,摇动时间自适应,图像始终保持在中间。开机后每摇晃10次切换下一组字模
/* 按了一下按键后变成了手动切换,直到回到第一组字的时候再自动切换
最后祝各位制作成功!学习进步!
