i want to control led with on and off buttons on php web page the moment i press on the php file called (index.php) send '1'( and '0' if off) to text file called (ledstatus.txt) then a file called (ledstatus.php) will connect with the arduino
now the problems are :
when i opened the serial monitor to check my output was :
connecting...
connected
HTTP/1.1 200 OK
Date: Wed, 12 Mar 2014 14:50:23 GMT
Server: Apache
Vary: Accept-Encoding
Connection: close
Content-Type: text/html
1
disconnecting.
first problem : i pressed on so it sends '1' then it disconnected
second problem : when i closed the serial monitor window the arduino resets it self
my codes:
( index.php )
<? if (isset($_POST['status'])) { $fh = fopen("ledstatus.txt", 'w') or die("can't open file"); $on = $_POST['status']; fwrite($fh, $on); fclose($fh); } else { $fh = fopen("ledstatus.txt", 'r'); $on = fread($fh, 1); fclose($fh); } ?> value="1">On value="0">Off(ledstatus.php)
<? $fh = fopen("ledstatus.txt", 'r'); echo fread($fh, 1); fclose($fh); ?>(Arduino script )

//Ethernet.begin(mac, ip);
// }
delay(1000);
Serial.println("connecting...");
if (client.connect(server, 80))
{
Serial.println("connected");
client.print("GET ");
client.print(page);
client.println(" HTTP/1.0"); // here I can adjust as suggested, using HTTP/1.1 and force a connection close
client.print("Host: "); // needed in my case (virtualserver)
client.println(host);
// client.println("GET /opelec/ledstatus.php?status= HTTP/1.1 200 OK");
// client.println("Host: www.jccdhr.org");
// client.println("Connection: close");
client.println();
}
else
{
Serial.println("connection failed");
}
}
void loop()
{
while (client.connected()) {
if (client.available())
{
boolean currentLineIsBlank = true;
String buffer = "";
char c = client.read();
Serial.print(c);
buffer+=c;
if (c == '1') {

// buffer="";
// else if (c == '\r')

}
}
if (!client.connected())
{
Serial.println();
Serial.println("disconnecting.");
client.stop();
//while(true);
}
}
}
ledstatus.txt is an empty file
and all the three files ledstatus.php , index.php , ledstatus.txt are on the webserver
and by the way excuse my english ![]()
thnx ![]()
