入手arduino和W5100已经有一段时间，朝着物联网的方向努力百度了好几天，试过Yeelink和乐联网均未成功，后来在一个百度贴吧中看到了这个帖子，抱着试一试的心态研究了一下，几经周折终于成功控制LED,在这里感谢[http://tieba.baidu.com/p/4500765226](http://jump.bdimg.com/safecheck/index?url=x+Z5mMbGPAs95UolpNuq+CwM2BpViN6QF0BYrUCVRu/eFc0EpxHr1IeHQfmNX6hX2O5wqAj/AHz4GDvE8C1MKNaPUJPlg5+nS1Bh2J5IcVUexTnSS3e1Wng5cTS2s56uVBKnEWaOOLx5z8Bn4gXBxDA8Zu4mdgY0)这个帖子的楼主给了我重生的希望![](http://tb2.bdstatic.com/tb/editor/images/face/i_f36.png?t=20140803)![](http://tb2.bdstatic.com/tb/editor/images/face/i_f02.png?t=20140803)

下面进入正题

第一先在 [http://www.lewei50.com](http://jump.bdimg.com/safecheck/index?url=x+Z5mMbGPAvE9iZcxuq5DzyPat3fA+S2WfITs42VX/XY7nCoCP8AfPgYO8TwLUwo1o9Qk+WDn6dLUGHYnkhxVR7FOdJLd7VaeDlxNLaznq5UEqcRZo44vHnPwGfiBcHEMDxm7iZ2BjQ=) 申请账号，估计这个大家都不用我教了吧
第二步在“我的物联”列表下的“我的设备”中新建设备如图，名字可以自己定义 ![](http://imgsrc.baidu.com/forum/w%3D580/sign=7ecfea637a0e0cf3a0f74ef33a47f23d/cdbff800baa1cd119c163551b112c8fcc2ce2d86.jpg)

第三
在“传感器与控制器”新建一个传感器如图，设备选择刚才新建的设备，标识就写led3
![](http://imgsrc.baidu.com/forum/w%3D580/sign=01542002f3f2b211e42e8546fa816511/3ad0262442a7d933d9f9a202a54bd11372f001d4.jpg)

第四，点击“智能物联”，点击 控制命令管理 ，新建两个命令
![](http://imgsrc.baidu.com/forum/w%3D580/sign=eee4f667c7fc1e17fdbf8c397a91f67c/8c5bb2504fc2d5622878919cef1190ef76c66c36.jpg)

![](http://imgsrc.baidu.com/forum/w%3D580/sign=0b5d3ed1fe03738dde4a0c2a831ab073/d0bece1190ef76c615b3ba5a9516fdfaae5167c5.jpg)

其中标题和方法名框中的都可以自己定义

第五
添加执行单元
执行单元管理新建两个
![](http://imgsrc.baidu.com/forum/w%3D580/sign=dbb0085fda1b0ef46ce89856edc551a1/6ed6e0ea15ce36d3aa4bc34132f33a87e850b1d3.jpg)

第六
自定义微信命令
![](http://imgsrc.baidu.com/forum/w%3D580/sign=845ebafe6481800a6ee58906813533d6/c260b88fa0ec08fa043b50d651ee3d6d55fbda6f.jpg)

第七

关键的一步来了，首先下载乐为的库文件，我整理了一下在这里 [http://pan.baidu.com/s/1nv92pvj](http://jump.bdimg.com/safecheck/index?url=x+Z5mMbGPAvVIlwZePSt0B3tEqEFWbC4tOatFxkC6cKxk439RfyFfMzjP89TiPYiXRDu7QJYkbWECKDoAhi0YiQg5Mc6dC0DBwl6yKPBk+ofrNsJLaxdGaKJF8obA7ltosrBkJqtQ7J2Pah4egTNMg==)

下载完成以后在 ![](http://imgsrc.baidu.com/forum/w%3D580/sign=afb1f0d5acc27d1ea5263bcc2bd4adaf/01f82a3b5bb5c9ea6e404192dd39b6003bf3b3f7.jpg)

这个文件夹新建一个leweiclient的文件夹把下载的文件复制到里面
第八

打开arduino IDE
点 文件，示例 ![](http://imgsrc.baidu.com/forum/w%3D580/sign=cbee7b7a53b5c9ea62f303ebe538b622/b4a810dbb6fd52662f637165a318972bd50736de.jpg)

打开以后修改自己的API，把下面的代码下载以后就可以试试了，微信也可以控制，有什么不明白的地方再联系我了扣扣三六九吧腰吧四六吧
