I would like some help with a project. I need to create an indicator board that will light LEDs when doors or open. One LED per door. It's a simple 12v circute with several door sensors, LEDs and resisters. I have a diagram, but I can't figure out how to upload it.
I would like to add the circuitry so that a pizo buzzer will buz for a second or two when ever one of the doors is opened. Not sure how to do it with several switch/Led/resister combinations in parrallel.
