Checking if arduino is connected if not restart

Hi, i am having a problem with my Ethernet shield not working after a couple of hours, so my solution is, when the arduino is not connected to the blynk server activate pin 4 which triggers relay tieing ground to reset then turning off pin 4.

  Download latest Blynk library here:

  Blynk is a platform with iOS and Android apps to control
  Arduino, Raspberry Pi and the likes over the Internet.
  You can easily build graphic interfaces for all your
  projects by simply dragging and dropping widgets.

    Downloads, docs, tutorials:
    Sketch generator: 
    Blynk community:  
    Social networks:  

  Blynk library is licensed under MIT license
  This example code is in public domain.

  This example shows how to use Arduino Ethernet shield (W5100)
  to connect your project to Blynk.

  NOTE: Pins 10, 11, 12 and 13 are reserved for Ethernet module.
        DON'T use them in your sketch directly!

  WARNING: If you have an SD card, you may need to disable it
        by setting pin 4 to HIGH. Read more here:

  Feel free to apply it to any other example. It's simple!

/* Comment this out to disable prints and save space */
#define BLYNK_PRINT Serial

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

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";

#define W5100_CS  10
#define SDCARD_CS 4

bool result;

void setup()
  // Debug console

  result = false;
  pinMode(3, OUTPUT);
  digitalWrite(3, LOW);
  digitalWrite(SDCARD_CS, HIGH); // Deselect the SD card

  // You can also specify server:
  //Blynk.begin(auth, "", 80);
  //Blynk.begin(auth, IPAddress(192,168,1,100), 8080);
  // For more options, see Boards_Ethernet/Arduino_Ethernet_Manual example

void loop()
  bool result = Blynk.connected();
  if (result = true);
      // engage reset function
      digitalWrite(3, HIGH);

Well, you do not need that last part, since after the reset… well… no more code running :stuck_out_tongue:

Other than that… is there a question about an issue?

BTW, there are simpler ways to do this without a relay…
