👨🏾 ➿ 🅿️ 网络灰姑娘的化妆。 Arduino周末项目。 LED睫毛 👨‍🔬 🍢 👓

设计师Tien Pham在旧金山的Maker Faire上首次展示了LED睫毛。那是两年前。好吧，几乎在阿里巴巴洞穴里，中国强盗开始以400甚至300卢布的价格出售类似物。

在图片中，这是两个带有十二个LED的薄印刷电路板，它们通过薄电缆连接到带有电池的控制板。使用特殊胶水将发光的睫毛固定在普通或假睫毛上，控制器和电池隐藏在头发中。技术上，乍一看，没有什么复杂的。但是！如果仔细观察一下睫毛板上的LED，则有12个，回路中只有3根电线。同时，LED不仅点亮或闪烁，而且像行车灯一样工作。我想知道半天他们是如何做到的。修改了一堆广告。而且，在慢动作中，事实证明LED可以成对执行任何效果。也就是说，任务立即缩小到控制三根导线上的六个LED。但是，三个！三分之六！再一次-六分之三。还有更多……然后他再次重复，答案以某种方式浮出水面。在这里-三个元素的所有排列数为6！

事实证明，微控制器在由三个导体组成的环路中分出了三个信号：零，一个和第三种状态。我们得到六个组合/排列，这意味着在每个排列中，六个LED之一点亮。如果它们包含在此方案中：

例如，点亮D2 LED。在A零，在B-第三状态，在C单元。仅D2 LED点亮！

现在开始微控制器输出上的零和一很容易。还有第三种状态？甚至更容易。设置输入模式。现在，高阻抗输入端（未拉至零或统一）实际上已与控制电路断开。

接下来是代码，动态控制微控制器的输出，打开任意数量的LED。最终，我们使行车灯闪烁，闪烁，熄灭。
以下是Arduino的代码，具有两个睫毛的效果，每个睫毛都有六组LED。

而这个女孩Veronica展示了这些效果。

也许对于某些人来说，这种管理方法早已为人所熟悉，而您已经在使用它。但是无论如何，真的很想分享。 Arduins应该喜欢它！
