I am looking to build a wired door monitor. I am a newbie to this.
I am thinking about something like this:
Normally Closed Magnetic switch attached to the door so that when the door is open it completes the circuit and lights a flashing red LED.
I was hoping this could be done using a single AA battery. I have searched the web and this forum but I guess this is too simplistic for anyone to have written it down.
Anyone have a diagram of what the circuit would need to look like and any parts I would need?
Thanks,
Bill
