  • LED nightlight that turns on in the dark

    The circuit remains on even if it is emitting no light. Consider using a 5v arduino power source.

    Play around with the resistors. You can probably replace the 1k with a 500ohm. Don't know for sure though

    Use a 2n2222. Almost any PNP will work.

    Only reason I replied is because I stumbled across this tutorial while searching for a nightlight tutorial for a friend. Cheers.
