Hi everyone!
I'm a complete beginner with electronics but I have an interesting project because my wife refuses to get a cat flap!
I've got a simple Infra Red detector outside which signals a wireless doorbell indoors when the cat triggers it. That works fine, except she constantly sets it off the whole time she's sat there and the <snip> thing keeps ringing, very annoying and the batteries only last about a fortnight, so...
Q: Is there some kind of switch or relay I can incorporate into the transmitter so that once it's triggered it turns off for X minutes?
Gratefull for any pointers or solutions,
THANKS
