行空板语音控制ESP32-C3台灯
本帖最后由 云天 于 2023-6-4 15:13 编辑【项目背景】
使用行空板加语音识别模块结合SIOT物联网平台，控制多个ESP32-C3台灯。编程软件使用Mind+和米思奇。
【项目准备】
1.改造台灯
将旧台灯内容，除电池，其它拆除，并将其中一根电源线剪断并引出，接到电磁继电器上的NO和COM端口。
电磁继电器接ESP32-C3的引脚5。
2.行空板连接WIFI并开启SIOT服务
获取IP地址：192.168.31.131
开启SIOT服务
新建“主题”：siot/DengKG
【行空板编程】
添加“语音识别模块”
【ESP32-C3编程】
ESP32-C3编程使用米思奇

物联网指令“1”、“0”控制一号灯开关。
注：需在米思奇软件目录：D:\mixly2.0-win32-x64-rc3\mixly2.0-win32-x64\resources\app\src\board\micropython_esp32c3\build\lib，放置simple.py文件。
