提问下语法方面
代码1的 40行 Stash stash;
按我理解应该是定义一个 Stash 型的变量（或实例）stash 但是 ...
stash是在库函数中声明的，主要用于构建数据包。建议不要用stash，用httppost比较好。我有个例子，你看看。不过最近没研究这个库了，好似又更新了不少。

那怎么获取上面的开关的数据来控制LED灯呢
使用HTTP GET的方式就可以了，教程可以参考 http://blog.yeelink.net/?p=94

使用W5100 制作的3种传感器 数据 上传yeelink成功，http://www.yeelink.net/devices/242
困惑于enc28j0,w5100在手，新手求代码
代码密集分布在bbs.yeelink.net和blog.yeelink.net上，本坛子里面也有不少的
yeelink.net的博客和论坛，都是基于enc28j60的，唯一一个5100还是测试光强的。我想先拿成熟的代码测试硬件，然后再慢慢学习和改进。
5100代码例程就有的吧。
yeelink官方的，不是5100+BH1750光强传感器模块，就是enc28j60+18B20,唯独没有5100+18b20的代码，而且例程质量远不如cosm
明天我写个例程给你。还好俺饿了好几顿，花了100块买了个5100
我是昏头呆脑，彻底迷茫在yeelink的例程，转投cosm已经小有斩获。
http://www.geek-workshop.com/thread-2563-1-1.html
至少说明，硬件是没有问题的，还是希望能回归yeelink.
我参照的是这个例程：http://arduino.cc/en/Tutorial/PachubeClient
其实更希望用下面这个例程，传输多个参数：http://arduino.cc/en/Tutorial/PachubeClientString
但是搞不明白读取18b20传感器部分，能不能援手点拨如何读取18b20。
yeelink这个官方例程，网络是通的，就是传感器部分不知道如何改写。
http://blog.yeelink.net/?p=34
DS18B20温度传感器的例程，两个都已经通过，可供参考
http://www.arduino.cn/thread-1345-1-1.html
问题是，此贴的网卡怎么修改为5100？
或者，下面这个官方例程，怎么把传感器部分，修改为单个18b20或者多个

哥们，W5100的使用，远远比enc的那个简单多啦！
收到，谢谢
回家就试，传感器A0，模拟输入么？
A0-A5也可以是数字，A6-A7是纯模拟
