i think my arduino might just be dying im not getting any serial data at all

SurferTim

Power down the Arduino and remove the ethernet shield. Power it up minus the shield and see if the serial comes back.

i think my arduino is just dying its been giveing me so much trouble
the serial data is sometimes glitched alot and now i receave no serial data at all that might be why the code works one minute then stops the next

How about posting all of your code (can't make much out of the various parts). How are you powering the relays (if powered directly from the arduino they may be causing the board to reset)? Below is very simple server code you can try and check if pin 5 goes hi/low from the web page using a multimeter.

Code: [Select]

//zoomkat 4-1-12
//simple button GET for servo and pin 5
//for use with IDE 1.0
//open serial monitor to see what the arduino receives
//use the \ slash to escape the " in the html, or use ' instead of "
//address will look like http://192.168.1.102:84 when submited
//for use with W5100 based ethernet shields

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

#include <Servo.h>
Servo myservo;  // create servo object to control a servo

byte mac[] = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED }; //physical mac address
byte ip[] = { 192, 168, 1, 102 }; // ip in lan
byte gateway[] = { 192, 168, 1, 1 }; // internet access via router
byte subnet[] = { 255, 255, 255, 0 }; //subnet mask
EthernetServer server(84); //server port

String readString;

//////////////////////

void setup(){

  pinMode(5, OUTPUT); //pin selected to control
  //start Ethernet
  Ethernet.begin(mac, ip, gateway, gateway, subnet);
  server.begin();

  myservo.write(90); //set initial servo position if desired
  myservo.attach(7);  //the pin for the servo control
  //enable serial data print
  Serial.begin(9600);
  Serial.println("server servo/pin 5 test 1.0"); // so I can keep track of what is loaded
}

void loop(){
  // Create a client connection
  EthernetClient client = server.available();
  if (client) {
    while (client.connected()) {
      if (client.available()) {
        char c = client.read();

        //read char by char HTTP request

          //store characters to string
          readString += c;

        }

        //if HTTP request has ended

          delay(1);

Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   8)
