Arduino control led via HTML

Hello everybady there ! Nice to meet you !
I have an arduino mega ,a wifishield ,a resistor and a led .So i want to create a buton and while i push it iwant the led state is on and else the led state is off .I know that i must write a code similar to the folowing :

#include <SPI.h>
#include <WiFi.h>

char ssid = “conn-x9e8bac”;

char pass = “a0ec809e8bac”;
int keyIndex = 0; // your network key Index number (needed only for WEP)

int status = WL_IDLE_STATUS;
WiFiServer server(80);

void setup() {
Serial.begin(9600); // initialize serial communication
pinMode(9, OUTPUT); // set the LED pin mode

// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println(“WiFi shield not present”);
while (true); // don’t continue

String fv = WiFi.firmwareVersion();
if ( fv != “1.1.0” )
Serial.println(“Please upgrade the firmware”);

// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to Network named: ");
Serial.println(ssid); // print the network name (SSID);

// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);
// wait 10 seconds for connection:
server.begin(); // start the web server on port 80
printWifiStatus(); // you’re connected now, so print out the status

void loop() {
WiFiClient client = server.available(); // listen for incoming clients

if (client) { // if you get a client,
Serial.println(“new client”); // print a message out the serial port
String currentLine = “”; // make a String to hold incoming data from the client
while (client.connected()) { // loop while the client’s connected
if (client.available()) { // if there’s bytes to read from the client,
char c =; // read a byte, then
Serial.write(c); // print it out the serial monitor
if (c == ‘\n’) { // if the byte is a newline character

// if the current line is blank, you got two newline characters in a row.
// that’s the end of the client HTTP request, so send a response:
if (currentLine.length() == 0) {
// HTTP headers always start with a response code (e.g. HTTP/1.1 200 OK)
// and a content-type so the client knows what’s coming, then a blank line:
client.println(“HTTP/1.1 200 OK”);

// the content of the HTTP response follows the header:
client.print("<a href="/H">ON

"); client.print("OFF ");

// The HTTP response ends with another blank line:
// break out of the while loop:
else { // if you got a newline, then clear currentLine:
currentLine = “”;
else if (c != ‘\r’) { // if you got anything else but a carriage return character,
currentLine += c; // add it to the end of the currentLine

// Check to see if the client request was “GET /H” or “GET /L”:
if (currentLine.endsWith(“GET /H”)) {
digitalWrite(9, HIGH); // GET /H turns the LED on
if (currentLine.endsWith(“GET /L”)) {
digitalWrite(9, LOW); // GET /L turns the LED off
// close the connection:
Serial.println(“client disonnected”);

void printWifiStatus() {
// print the SSID of the network you’re attached to:
Serial.print("SSID: ");

// print your WiFi shield’s IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");

// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print(“signal strength (RSSI):”);
Serial.println(" dBm");
// print where to go in a browser:
Serial.print(“To see this page in action, open a browser to http://”);

.I think that it will be able to do this with the onmousedown and onmouseup .
Can everybody help me ?

I think that it will be able to do this with the onmousedown and onmouseup .

Why do you think that? button objects are form child objects. You don't have a form.

No i don't have a form can you help me ?

can you help me ?

I tried. I pointed you to the best site on the internet to learn how to develop html pages. It's up to you to learn how client/server applications work, and to learn how to exchange data between a client and a server BEFORE you try to make the Arduino a client or a server.

Jonnyhunter: No i don't have a form can you help me ?

Sure, open the below web page then look at the source code. No forms. ;)
