我介绍了去年万圣节的 led 眼球

当我抓住抓地力时, 我把一个带有 led 胶带的夹子贴在魔手前面的眼睛形状上, 从而眨眼。瞳孔是枪口, 它也转动, 并且财产手申请!

配置

部分

Microcontroller Arduino Pro Mini 328 5v 16MHz

　
Bending sensor 55mm

　
Full color serial LED tape Neopixel

　
Slide switch

设备概述

这个眼球装置有抓地力和扳机。我是通过改造大索的魔手来做到的。

当可变阻力10kohm 被压到抓地力和枪口时, 眼球的眼睛向左和向右移动。
当你扣动扳机时, 在魔法手的手部分训练的弯曲传感器闪烁。

发光二极管眼球

一个包裹涂在一个颜色的大索, 以附加 led 胶带 ne鸦片 xel 的眼球类型。

　
Neopixel 使用68个细胞。接线顺序如下所示。

工作模式

该设备配备了两个滑动开关, 操作模式会发生变化, 如下表所示, 具体取决于开关状态。

演示模式: led 像 Neopixel 库示例代码一样发光
学生颜色更改模式: 使用手柄更改瞳孔颜色
调光模式: 通过抓地力改变了导光能

arduino ide 代码

使用了以下 Neopixel 库:
