Hi folks
I Have been hunting around all day for an answer to my circuit problem. I am glad to have found this site as it seems an educational gold mine in this area.
This is probably a stupid question that I should already know the answer to but in my amateur circuit work i have never got round to learning this.
Basically for a number of years I have used this useful relay circuit to switch on a 9v door spyhole camera. I have the sensor leads going to one button which actuates the relay while the reset switches it off. I also have the 9vDC power adapter which powers the camera, powering the relay circuit. This has worked good for years however I have persistent problems forgetting this camera is on as there is no indicator to say so.
My question is HOW do I insert a small LED in this circuit to light when the relay is on and turn off when the reset is pushed. ( a power indicator light )
Any help on this would me very much appreciated.
