炫书包
小学毕业的儿子准备上中学了，自己搜索选购了一 款“我的世界“夜光书包。受其发光警示作用的激发~夜路更安全，我决定用LED灯带和传感器给它添点炫酷效果。
【简单功能】
1.根据环境光强自动决定开关炫彩（随机七种）灯光
2.蜂鸣声音提示背后7米左右有人尾随
3.触摸开关可切换关闭蜂鸣提示
【材料清单】
1.炫彩 WS2812 LED灯带2.模拟环境光线传感器3.数字蜂鸣器模块4.人体热释电红外传感器5.数字触摸开关Touch6.UNO+IO传感器扩展板【实验用方便】7.Cheapduino控制器【书包用简洁】8.电源、开关、线材
【信号线针脚图】
【盖住环境光传感器模拟黑夜】

【Arduino 代码】 注：书包上的控制器最好选CheapDuino,小巧，低功耗，可用旧手机电池（3.7~4.2V）
