I'm making a site with the arduino and when I add more lines of code (more precisely "println") fails to make the site load.
The code follows below:
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address and IP address for your controller below.
// The IP address will be dependent on your local network:
byte mac[] = {
0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress ip(169,254,190, 177);
// Initialize the Ethernet server library
// with the IP address and port you want to use
// (port 80 is default for HTTP):
EthernetServer server(80);
void setup() {
// Open serial communications and wait for port to open:
Serial.begin(9600);
// start the Ethernet connection and the server:
Ethernet.begin(mac, ip);
server.begin();
Serial.print("server is at ");
Serial.println(Ethernet.localIP());
}
void loop() {
// listen for incoming clients
EthernetClient client = server.available();
if (client) {
Serial.println("new client");
// an http request ends with a blank line
boolean currentLineIsBlank = true;
String vars;
int varMenu=0;
int var2Menu=0;
int var2Dig=0;
int var3Dig=0;
while (client.connected()) {
if (client.available()) {
char c = client.read();
Serial.write(c);
vars.concat(c);
if(vars.endsWith("=Entradas")) varMenu=1;
else if (vars.endsWith("=Matlab")) varMenu=2;
/*else if (vars.endsWith("=EMail")) varMenu=3;*/
/*else if (vars.endsWith("=2on")) var2Dig=1;
else if (vars.endsWith("=2off")) var2Dig=2;
else if (vars.endsWith("=2on")) var3Dig=1;
else if (vars.endsWith("=2off")) var3Dig=2;*/
// if you've gotten to the end of the line (received a newline
// character) and the line is blank, the http request has ended,
// so you can send a reply
if (c == '\n' && currentLineIsBlank) {
// Cliente terminou de comunicar e o arduino tem de enviar
// o seguinte cabeçalho para o browser

For example:
if (varMenu==0) //MAIN
{
client.println("<h1>Projecto Final</h1>");
client.println("Trabalho realizado usando um Arduino UNO R3 + Ethernet Shield");
client.println("<h3>Objectivo do site:</h3>");
client.println("- Neste website e possivel activar as entradas/saidas do arduino independentemente.

If I delete the comment the site does not work.
Someone can help me with the code or tell me a better way to program?
