先说写贴原因，最近空了下来，看到一堆买来没有用的8266，心血来潮到论坛看看，看到不少好帖子，又想到家里小爱同学吃灰状态，就想起利用起来！
构思：利用8266控制家里的电脑开关机，家里有孩子喜欢玩游戏，为了方便管理再加个DHT11放到机箱测温，就知道电脑的开关状态了。后来看到帖子说可以学习遥控器，就想加上此功能，就不需要到处找遥控器了，家里孩子总是乱扔，我的手机是小米的有遥控功能，但是我老婆的没有，现在顺便做一下这个功能，在这感谢@zhangjunyan同学，我之前也是搞维修的，看你的帖子很亲切。
实施：只需要将6266的控制脚默认高电平，控制开关机时只需要delay一段时间的低电平就可以了，（一秒以内为好我的是600毫秒左右）。接PC的power脚正极就可以了（别忘了pc的负极也要接8266的负极）因为我的8266取电是从USB取得的，所以我这里没接。dht供电3.3这里注意一下，红外接收头我正好学习套件有，发射头拆的报废遥控器，
