the relay uses a 12v coil, but the same steps apply to using a 9v one

Here the code you could use:

/***********
connect an NPN transistor driving a motor to pin 9 on arduino
***********/

int motorPin = 9;

void setup() {
pinMode(motorPin, OUTPUT);
delay(45000);
digitalWrite(9, HIGH);
delay(1000);
digtalWrite(9, LOW);
}

void loop() {
}
