I have a door that needs to be closed all the time, and if it's left
open I want a buzzer to beep for a bit, it could beep constantly till
the door is closed. It's to assure the house animals don't go into my
office which seems to be their favorite place to chew up cables, etc.
Short of getting rid of them I wanted to create some type of alarm
circuit with magnetic switch than when OPEN a buzzer will sound.
Found a couple of the web but they all seem so complicated?
If the door if open for about 20-30 seconds want it to beep!
Thansk!
