Arduino Duemilanove

Hello all,
This is the test code for a pir control relay circuit.

Arduino sketch to turn relay on for a set period of time when triggered by a source. In this case, it is a PIR motion sensor.

Thanks!

// pins for Arduino Duemilanove
int irmotionPin = 11; // Pin of IR Motion
int relayPin = 13; // Pin of  relay
// const timeleft = 600;

void setup() {
  // loop from the lowest pin to the highest:
    Serial.begin(9600);
    pinMode(relayPin, OUTPUT);
    digitalWrite(relayPin, LOW);
}

void loop() {
  // loop from the lowest pin to the highest:
  while (digitalRead(irmotionPin) == HIGH){
  digitalWrite(relayPin, HIGH);// Turn Relay on

for (int hrs = 0; hrs > -1; hrs--) {
     for (int mins = 5; mins > -1; mins--) {
      for (int secs = 59; secs > -1; secs--) {
        Serial.print("Relay timer ON ");
        if (hrs<10){Serial.print("0");}else{Serial.print("");}
        Serial.print(hrs);
        if (mins<10){Serial.print(":0");}else{Serial.print(":");}
        Serial.print(mins);
        if (secs<10){Serial.print(":0");}else{Serial.print(":");}
        Serial.println(secs);
        delay(1000);
      }
     }
    }
  }

digitalWrite(relayPin, LOW);// Turn Relay off
      Serial.println("Relay is OFF");
      delay(500);
}
