Yeelink arduino uno + W5100 实现11个LED开关点亮

这段代码原本是 论坛：风生水起、口腔（戴志强）等，然后我再修改。

有几个问题请大家帮忙：
1、    if (flag < 11) ///更改为开关的个数
    {
      //get data from server
      getData();
    }
    else
    {
      //put data to server
      if (flag = 12) {
        flag = 0; ///更改为开关的个数+1
      }
这部分代码不明白作用，但对整个有影响。请问我要加入LM35上传数据，应该怎样修改。

2、D18、D19数字口，不知为什么无法控制。（初步验证，Yeelink的网络传输是正常的，是UNO主板的D18、D19（A4、A5）数字端口的电平电压过分的低，不知原因，更换其它UNO主板问题都一样。而且这两个口的会被其它数据口的开关控制着、联动）10、11、12、13号端口用于SPI通信；  4号端口用于TF卡片选； 10号端口为W5100片选；


2014/12/13 发现W5100主板会有死机现象，LED灯开了就关不了，不知是主板问题还是代码问题。

上视频吧，读代码多枯燥啊

这个还是比较厉害的！！！！！哟哟一定的使用价值！！！

你不是买的r3网卡吗.

你不是买的r3网卡吗.

W5100 R3版本的 就正常

if (flag = 12) {
        flag = 0; ///更改为开关的个数+1
      }
是不是是应该换成falg ==12呢？这是错误吧？

而且我想知道我随机打开开关也是可以控制的，那flag的作用是用来干嘛的，按顺序才能打开灯吗

if (flag = 12) {
        flag = 0; ///更改为开关的个数+1
      }

这个我也觉得是个问题。。。。。。

纳尼为什么你控制那么快，我才带了六个灯就延迟很厉害

雨轩

怎么将DHT11加上去，代码怎么样，谢谢！
