ESP8266远程定时打氧机

起因是家里养了一些小鱼需要打氧，但是又不需要24小时全天候的开着，电机的声音实在是太吵了，就想着能不能做个定时开关给它，在网上看到esp8266这个单片机功能好像挺多的，而且也不需要什么技术含量就可以做，于是就在淘宝上买了一套(esp8266/继电器底座/USB烧录器)，这个价格真的是爱了！

买回来肯定是不能直接使用的，需要给他刷写程序，得让它连上网络，在收到指令做出相应的动作，所以需要用到一些工具，也可以去官网下载完整版(百度网盘2个多G，太折磨人了)
下载软件包，解压到"D:\mixly\"根目录，不要有中文和特殊符号，然后点一键更新.bat

期间会提示安装单片机依赖，y回车(选装8266即可)

安装完成后，双击打开软件主程序"Mixly.exe"

右边点击找到esp8266这个型号点进去

找到设置→库管理→巴法云esp8266扩展库

进入 巴法云官网 注册一个账号，然后进入工作台。创建一个主题，xxxx001

在左边工具添加这些代码块，填入自己的WiFi名称密码和巴法云私钥。

当然你也可以用我编辑好的dome下载导入填写信息后上传即可。

又或者粘贴代码

然后在上面工具栏找到你的端口COMx，最后点击上传等待完成即可

最后最后一步就是接线方面，如下图：
