Arduino Ethernet w5100 Shield Connection Problem

[liamo_08]

Hi all, my connection works just fine after either being uploaded or reset pressed but after a while of inactivity (hour or 2), I need to reset the arduino to regain connection as I get the error “arduino uno is offline”.

My code is as follows:
(it turns the heating on for either 1 hour or 3 hours)

#define BLYNK_PRINT Serial // Comment this out to disable prints and save space
#include <SPI.h>
#include <Ethernet.h>
#include <BlynkSimpleEthernet.h>
#include <SimpleTimer.h>

char auth[] = “325f0348e76c4a759330d8940d95d764”;

int pin3; //to read pin3
int pin4;
int x; //for the counter
int led= 9;

// the setup function runs once when you press reset or power the board
void setup()
{
// initialize digital pin 13 as an output.
Serial.begin(9600);
Blynk.begin(auth);
pinMode(3, INPUT);
pinMode(4, INPUT);
pinMode(led, OUTPUT);

x=0;

}

// the loop function runs over and over again forever
void loop()
{

Blynk.run();

////////////////////////////////////////////////////////Turn on heat for 4 hours/////////////////////////////////////
pin4= digitalRead(4);

if (pin4==HIGH && x<14400) // run 5 loops at 1second each

{
Serial.println(‘1’);
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
x=x+1;
Serial.println(x);

}// wait for a second
else
{
digitalWrite(led, LOW);

}

if (pin4== LOW)
{
x=0;
}
/////////////////////////////////////////////////////Turn on heat for 1 hours//////////////////////////////////////////
pin3= digitalRead(3);

if (pin3==HIGH && x<3600) // run 5 loops at 1second each

{
Serial.println(‘1’);
digitalWrite(led, HIGH); // turn the LED on (HIGH is the voltage level)
delay(1000); // wait for a second
x=x+1;
Serial.println(x);

}// wait for a second
else
{
digitalWrite(led, LOW);

}

if (pin3== LOW)
{
x=0;
}

}

ALWAYS wrap your code by pressing this magic button (Backtick`) 3 times (before the code and after it):

This makes your code beautiful with highlighted syntax, like this:

//comment goes here
void helloWorld() {
   String message =  "hello" + "world";
}

You can also select the code and press </> button in the top menu:
