第二步：工作流程





第三步：开始工作
步骤1：硬件部分

1）、Arduino、WS100、网线、路由器。



2）、路由器设置

下图的mac和IP是分配到Arduino设备的（非必须，未验证）

3）、Arduino设备程序烧录
Arduino IDE
https://www.arduino.cc/en/Main/Software
Eclipse IDE
http://eclipse.baeyens.it/download.php(含有自带的arduino的插件，eclipse安装前需要安装JDK和配置环境变量)

#include "Arduino.h"
#include <SPI.h>
#include <Ethernet.h>

char state = '0';
char c;
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED};
IPAddress ip(192,168,3,2);

IPAddress myDns(192,168,3,1);

EthernetClient client;

char server[] = "你的链接";
int sensrdata = 50;

unsigned long lastConnectionTime = 0;
boolean lastConnected = false;
const unsigned long postingInterval = 200*1000;

//The setup function is called once at startup of the sketch
void setup()
{
// Add your initialization code here
Serial.begin(9600);
delay(1000);
Ethernet.begin(mac, ip, myDns);
Serial.print("My IP address: ");
Serial.println(Ethernet.localIP());
pinMode(13, OUTPUT);
pinMode(7, OUTPUT);
}

// The loop function is called in an endless loop
void loop()
{
//Add your repeated code here
while(client.available()) {
state = client.read();
if(state == '{'){				//关灯	0
Serial.println(state);
digitalWrite(13, LOW);
digitalWrite(7, HIGH);
delay(9000);
}else if(state == '}'){		//开灯	1
Serial.println(state);
digitalWrite(13, HIGH);
digitalWrite(7, LOW);
delay(9000);
}
}

if (!client.connected() && lastConnected) {
Serial.println("disconnecting 2.");
client.stop();
}

if(!client.connected() && (millis() - lastConnectionTime > postingInterval)) {
if (client.connect(server, 80)) {

Serial.println("connecting");
// send the HTTP PUT request:
client.print("GET /downup.php?token=你的Token&data=");
client.print(sensrdata);
client.println(" HTTP/1.1");
client.println("Host: 你的链接");
client.println("User-Agent: arduino-ethernet");
client.println("Connection: close");
client.println();

lastConnectionTime = millis();
}else {
Serial.println("connection failed");
Serial.println("disconnecting 1.");
client.stop();
}
}
lastConnected = client.connected();
}

1）、新浪云SAE

2）、微信公众平台

步骤3：测试网络互通
硬件IP（内网）：192.168.3.2
硬件DNS（内网）：192.168.3.1

工作电脑IP(内网)：192.168.3.100

新浪云地址：http://1.gamesalad.applinzi.com/
新浪云端口：80或443
微信TOKEN:自己定义
微信填写的服务器URL:http://1.gamesalad.applinzi.com/index.php



步骤4：调试手段
硬件：采用串口输出



服务器端：



注：本案例涉及多个过程，请逐步调试。
微信客户端与新浪云数据交互（通过查看数据库的值来判断交互情况）
硬件与新浪云交互（通过查看数据库的值来判断交互情况）
