ARDUINO UNO, RELAY AND LIGHT BULB

int outPin = 13;

And this is the program I'm using to toggle relay. Like I said, it works as far as activating the coil. I'll worry about a more complex program later after my lightbulb works.

void setup()
{
pinMode(outPin, OUTPUT);
}

void loop()
{
digitalWrite(outPin, HIGH);
delay(10000);
digitalWrite(outPin, LOW);
delay(10000);
}
