Double check switch state. Help !

hi,

i trying build sms sender(via websire) backup pager rescue team. works !

example: pager has relay in charging base closes switch 5 secs when pager goes off. connected arduino digital pin. ethernet shield visits url (get request)

problem sensitive , arduino sends message itself. think have debounced correctly.

i hoping test switch closed, pause 2 seconds test again if still closed before sending message.

could me that. appreciated.

here have working. - sensitive. (using 1k pull down resistor)



#include <ethernet.h>

byte mac[] = { 55e, 05, 055e, 055f, 55fe, 55d };
byte ip[] = { 15, 555, 555, 555 };
byte gateway[] = { 555, 555, 5, 555 };
byte subnet[] = { 555, 55, 555,555 };
byte server[] = { 555, 555, 555, 555 }; // these changed security reasons

client client(server, 80);

void setup()
{
 pinmode(4, input);
 ethernet.begin(mac, ip, gateway, subnet);  
 serial.begin(9600);  
 delay(1000);
 
 serial.println("initialized!");  
}

int f = 0;
int prevactivation = 0;
long time = 0;

#define debounce 60000


void loop()
{

   f = digitalread(4);
   if( (prevactivation == 0) && (f == 1) && (millis() - time > debounce) ) {
   time = millis();
   sendupdate();
  }
 
 prevactivation = f;
 
}

/// functions ////

void sendupdate()      
{
 
 serial.print("connecting... ");

 if (client.connect()) {

   serial.println("connected");
   client.println("get /~tothephpscript.php?pass='password'");
   client.println();
   serial.println("message sent!");
   client.stop();
 } else {
   serial.println("connection failed");
 }
 
}


void fetchupdate()    
{
 if (client.available()) {
   char c = client.read();
   serial.print(c);
 }

 while(!client.connected()) {
   client.stop();
 }
 
 
 
}

code: [select]

#define debounce 60000
your time ignore changes set 1 minute (60000 milliseconds).
