[已解决] 求解 web控制uno+opnwtr+w5100 问题

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

byte mac[] = {
  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(192,168,1, 177);
int ledPin7 = 7;
char cc = ' ';
char ccc = ' ';

EthernetServer server(80);

void setup() {
  Serial.begin(9600);
while (!Serial) {
;
  }
  pinMode(ledPin7, OUTPUT);
  Ethernet.begin(mac, ip);
  server.begin();
  Serial.print("server is at ");
  Serial.println(Ethernet.localIP());
}
void loop() {
  EthernetClient client = server.available();
  if (client) {
Serial.println("new client");
boolean currentLineIsBlank = true;
while (client.connected()) {
   if (client.available()) {
      char c = client.read();
      Serial.write(c);
      if (c == '\n' && currentLineIsBlank) {
      // send a standard http response header
      client.println("HTTP/1.1 200 OK");
      client.println("Content-Type: text/html");
      client.println("Connnection: close");
      client.println();
      client.println("<!DOCTYPE HTML>");
      client.println("<html>");
   // client.println("<meta http-equiv=\"refresh\" content=\"5\">");
      for (int analogChannel = 0; analogChannel < 6; analogChannel++) {
         int sensorReading = analogRead(analogChannel);
         if (analogChannel == 1)
         {
          int A1 = analogRead(analogChannel);
          int guangqiang = A1;
          client.print(guangqiang);
         client.print(":");
      }
      else
      if (analogChannel == 2)
      {
      int A2 = analogRead(analogChannel);
            int wendu= (A2*0.0048828125*100);
      client.print(wendu);
         }
      }
      client.println("</html>");



   //  byte c = client.read();
      if(c == 'O' && cc == '=')
      {

if(ccc == 'X')
            {
   digitalWrite(7,HIGH);
            }
   else if(ccc == 'Y')
            {
   digitalWrite(7,LOW);
            }
      }
      ccc = cc;
      cc = c;
   break;

}
      if (c == '\n') {
      currentLineIsBlank = true;
      }
      else if (c != '\r') {
      currentLineIsBlank = false;
      }
   }
}
delay(1);
client.stop();
Serial.println("client disonnected");
  }
}
下位机代码 web里能收到返回的温度值，但是web给UNO发指令 uno无反应:'(。求解~求大神。。。

如下来自my friend： Jose from Spain

Step 1;
Add a button form in his page:
http://www.w3school.com.cn/tags/tag_button.asp

<form action = "" method = "post">
<button type="ArduinoAction">Click Me!</button>
<form>

step 2:
(pseudocode)

similar to line 24, if ( c = ArduinoAction ) turn on LED
