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。

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。

调试过程

  • 程序下载

Microduino-Core+/zhMicroduino-USBTTL/zh堆叠在一起.用数据线将写好的程序通过Microduino-USBTTL/zh上传到Microduino-Core+/zh上。 注意:最好不要将所有模块堆叠在一起之后再上传程序

Download1.jpg

找到该程序的物理位置,"语音情景灯/ EGGROOM/ EGGROOM.ino",双击即可

搭建

搭建硬件电路,将用到的设备叠加起来(无上下顺序) Microduino-Core+ Microduino-USBTTL Microduino-BT(4.0) Microduino-BM Microduino-Duo-H Microduino-sensorhub Microduino-Lamp 锂电池

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

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)

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

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
