Bluno控制灯带
最近到手一套蓝牙炫彩LED灯带套件，听起来就酷的不行。。。正直双蛋期间，可是我木有圣诞树做装饰，暂且只能玩玩灯带，还望各位看官忍受一下
1、套件清单
BLUNO控制器 1个模拟声音传感器 1个音频分析模块 1个3米WS2812灯带 1条传感器扩展板V7 1个电源转接头 1个5V@3.6A电源适配器1个

3、编程控制（用的官网代码示例）
first sample，不用蓝牙模块，也不需要传感器，效果如下图

second sample，Bluno蓝牙控制，嘎嘎
这个是可以通过手机app来控制的，当手机与Bluno蓝牙配对连接后就可以控制了，app的下载网址http://www.dfrobot.com.cn/goods-823.html
app界面如下（箭头所指处事蓝牙连接）
