I realize that this is of topic, but i figuret that the moders would be able to help me out.
I am trying to make a fake alarm, with a blinking red LED. But I dont exactly know how to wire my relay. It is RadioShack #275-249.
I would draw a schematic, but i dont exactly know how to do it, and make it understandable. It dose have a picture on the back, but i allready tryed what i thought would work, with noi sucess. any help wiriing this realy wold be apriciated.
Also, how do I calculate what size resistor to use?
