    I got one of these relays for free. Anyone have any ideas on how or if I can use it with the Defusable clock for a siren and or a lighting effect?

    Hmm, it looks like it requires 12V to operate. The ATmega328 output pins are 5V. I suppose you could have an output pin control a transistor which controls the relay.
