Hi i really am a newbie and need some advice.
i have a pir floodlight which lights on when theres movement outside.
I want to install/build something that makes an audible noise when the light goes on.
BUT only for a set time amount e.g. 5-10 seconds.
my original idea was to use a relay and have a small dc circuit to kick in with the buzzer.
but not sure how to do timing ?
any help/advice is appreciated
