This circuit uses a switch with a transistor to reverse the N.O. or N.C. function of a sensor (the switch)

I needed the reversed signal of a photo resistor and decided this was the best way to do that without getting to complex or buying new parts.

Hahahah, I mean, you would need to add a resistor. I just wanted to illustrate the logic. Cheers mate.

You power the leds through the base emitter junction. Wtf never seen that before...

what you trying to make? I did a similar behavior using one NPN and one PNP, i use it as a dark sensor for my solar panel battery charger http://everycircuit.com/circuit/4744183993860096
