    Hi Could anybody help me please, i'm making a buzzer game for the village fete and am stuck with the wiring. I've made the wire and a buzzer is working but what i would like to do is have three lights that come on one by one as the wire is touched, also when the third light is on a siren comes on and stays on. I'm tring to use a 12v car battery as 230v is not very close by, i have the buzzer, siren and can get lights what else do i need?

    Can anyone do a wiring diagram (a simple one please) for me.

    Thanks.

    Be really careful not to short the car battery (let the positive and negative leads contact each other) it can be very dangerous as they can dump a lot of amps right away. I've heard from a lot of people that have had them explode and send battery acid everywhere, so it's no joke. Can you test your circuit with a smaller 12V battery or wall wart power supply?

    Read the LED's, and chasers eBook chapter on this site for how to do delay's with the lights.
