Hi guys this alarm uses a reed switch to turn on a siren when a door or window is opened.
I'm wondering how I could tweak it so even after the magnet lines back up (door / window closed) the alarm keeps sounding for a certain amount of time around 5-10 seconds.
Here's the circuit I couldn't find anything on the ic used
