==实验原理==
语音情景灯模块的原理是记录语音和情景的一一映射关系，通过拼音识别输入的语音，返回给核心对应的情景编号，核心根据得到的情景编号，通过模拟口控制灯光模块每盏led灯的亮灭，实现不同情境下的不同颜色组合。
整个灯光控制系统包括四个部分：
*供电系统
使用[Microduino-BM]电源管理模块和外接电池组合为语音灯供电
*中央处理器
中央处理器是语音情景灯系统的核心。采用[[Microduino-Core+]]作为核心。
*无线通讯
语音情景灯系统采用Bluetooth无线通讯方案，使用[Microduino-BT(4.0)]模块，通讯速度响应快，在空阔地域的控制范围大概8米左右。
*语音控制
采集并识别语音内容。

*主要传感器
*[[Microduino-Lamp/zh]]
套件使用Microduino-Lamp模块作为发光设备，该模块级联了6盏RGB3色彩灯，并可以使用相应的库函数控制每盏彩灯的颜色，为了清晰说明彩灯的控制方法，用一个简单的程序举例。
打开Arduino IDE，在文件（File）—>示例（Examples）—>_99_LCD_NeoPixel目录下，点开例程strandtest。

安装发光二极管
将发光二极管的负极插在[[Microduino-Sensorhub/zh]]传感器扩展模块的A7管脚，正极插在SDA管脚
[[File:Emotionlight2.jpg||600px|center]]
将传感器数据线插入第三行第一列插槽，观察这里插线的部分，4根线从左到右分别是GND，VCC，D2，D3接脚（不要看颜色，实物颜色可能与本例不同）
[[File:Voidsensor0.jpg||600px|center]]
[[File:Voidcesensor1.jpg||600px|center]]
安装语音话筒
语音话筒无正负极，将两端分别插在语音传感器的MIP和MIN上即可
[[File:Voidesensor2.jpg||600px|center]]
[[File:Voidsensor3.jpg||600px|center]]
==注意问题==
*每次语音输入命令，都要先说f1对应的内容，本例是“美科”读者可根据自己的设置输入
*二极管极性的判断，反接的话二极管不会发光
