Congos to Robtillaart! anywhere in the world! if he's listening.

Folks used some French it seems , my translator isn't working right ,seems I have lost the fun!

What did the anode say to the cathode?

Why are you so negative?

hahahahahhohohoho

Sheesh! you are lucky man.

Look at me : I wrote WANTED! A Girl with LOVE for me and Arduino! and its been a Tonn posts since then STILL I'm SingleTONN , HAHA  

Have you seen the line of boards sold by Olimex (Olinuxino)?

Cheap good things, uses popular processors BUT boards from them are not so popular among the developer as compared to the likes of BeagleBone or the RPi or other TI sitara based complete development system

Geoff,

Thanks for getting back I already use the phone chargers and etc very easy and good working cheap wallwart adapters but the problem that In my implication the space available is pretty much less and I need a small solution I understand that a couple or passives definitely need to go in the circuitry.

Hi Folks,

Need to drive AVR's with power coming from wallwart , I have the option of using a transformer but that is a big size solution! so anything out there you are using that is akin to a IC and converts from wallwart AC (120VAC/250VAC) to DC 5 volt logic level?

Now I'm able to find the file:

here's the error in Php file that IM getting now:

Code:

[@ SurferTIM , I added your code and its below(just commented out>> client.println("HOST: winacro.com")]

@ SurferTIM , I added your code and its below(just commented out>>    client.println("HOST: winacro.com")

Code:

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

int relayPin = 9;
char Str[11];
int prevNum = 0;
int num = 0;
long onUntil = 0;
int connectLoop;

long pollingInterval = 5000; // in milliseconds
long onTime = 60000; // time, in milliseconds, for lights to be on after new email or comment

// Enter a MAC address for your controller below.

byte mac[] = {  0x90, 0xA2, 0xDA, 0x0D, 0x78, 0xE1 };
char serverName[] = "winacro.com";



// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;

void setup() {
  Serial.begin(9600);
  pinMode(relayPin, OUTPUT);
  // start the Ethernet connection:
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // no point in carrying on, so do nothing forevermore:
    while(true);
  }
  // give the Ethernet shield time to initialize:
  delay(2000);

}

void loop()
{
    Serial.println("connecting...");

  // if you get a connection, report back via serial:
  
  if (client.connect(serverName, 80)) {
    Serial.println("connected");
    // Make a HTTP request:
    client.println("GET /PHP/email.php HTTP/1.1");
    //client.println("HOST: winacro.com");
    client.println();
    int timer = millis();
    //delay(1000);
  }
  else {
    // if you didn't get a connection to the server:
    Serial.println("connection failed");
    
  }
// if there's data ready to be read:
  while(client.connected())  {
    while(client.available())    {
      char inChar = client.read();
      Serial.write(inChar);
      // set connectLoop to zero if a packet arrives
      connectLoop = 0;
    }

    connectLoop++;

    // if more than 10000 milliseconds since the last packet
    if(connectLoop > 10000)    {
      // then close the connection from this end.
      Serial.println();
      Serial.println(F("Timeout"));
      client.stop();
    }
    // this is a delay for the connectLoop timing
    delay(1);
  }

  Serial.println();

  Serial.println(F("disconnecting."));
  // close client end
  client.stop();  
  if(num > prevNum) {
      Serial.println("New Comment.");
      digitalWrite(relayPin, HIGH);
      prevNum = num;
      onUntil = millis() + onTime;
    }
    else if(millis() > onUntil)
    {
     digitalWrite(relayPin, LOW);
    }
  //delay(pollingInterval);
}

and I get the following with it:

if i keep the     client.println("HOST: winacro.com"); then i'm not able to connect!

I am more confident with Arduino team's ability to write a decent firmware and library than other makers also.

RN-171 and other many flavors are from MicroChip and you know microchip is the best when it comes to good quantity manufacturing  and thus cost gets dropped, neverthless this is my analysis.

Sir Liudr,

I think the Arduino WiFi shield doesn't have that kind UART communication facility everything needs to work through its library!
The biggest thing working with a ARduino WiFi shield is its cost at the very first time I was turned down with it, Learning to work with something which will hardly have any end product place is not good , and in case of Arduino WiFi shield this is the case because of its cost, I that's why picked up a RN-171 and Now im eyeing that very cheap TIcc3000 chip that can go upto $10 for 1000 pcs that's pretty cheap when it comes to connecting anything to the Internet!

edit: Your web server is in "real world". If it failed while the Arduino was waiting for the response, and you had no timeout, that would have been a fail on the Arduino also.

I'm also running my website side by side to see if its caused by my webserver fail or my Arduino problem (while my code is certainly having problems as you pointed out) but right now anything isn't working because my 8 Dollar per year web space is down!

ANOTHER thing is that Im going to remove the following snippet from my code and replace it with your Above recommendation!

Code:

// if there's data ready to be read:
  if (client.available()) {
     int i = 0;
     
     //put the data in the array:
     do {
       Str[i] = client.read();
       i++;
       delay(1);
     } while (client.available());
     
     // Pop on the null terminator:
     //Str[i] = '\0';
     //convert server's repsonse to a int so we can evaluate it
     Serial.print(Str);
     num = atoi(Str);
     delay(2000);
     Serial.print("Server's response: ");
     Serial.println(num);
     Serial.print("Previous response: ");
     Serial.println(prevNum);
     if (prevNum < 1)
     { //the first time around, set the previous count to the current count
      prevNum = num;
      Serial.println("First comment count stored.");
     }
     if (prevNum > num)
     { // handle if count goes down for some reason
      prevNum = num;
     }
  }
  else
    {
     Serial.println("No response from server.");
    }

Only if you don't want to take the time to do it right. But then you already have a headache, so what will it matter?  

Nah! man.. thanks for keep coming back

SHIT! now my webserver went down!

@SurferTIM-> I would just try delaying a few seconds after that part you pointed out in the same code I have and then come back to you!

Liudr Sir,

I'm doing great I hope you are fine too!

I have good experience with WiFi so I would say the UART based wiFi modules from  Roving networks are a LOVE affair I recently wrote a Android App doing TCP/IP and all I needed to handle in Embedded side of system is UART comm of the wifi chip with that of the ATmega, great little thing.
Which WIfi chip is there on your Shield?
