guys
i need your advice here. i want to incoparate my security system with a knocking sysytem and i would like to know if what i am thinking is possible. i want to include a knocking system and i have thought of using a electrect microphone element as a speaker to listen to a special sequence on knocking. the thing is you knock lets say 3 times then the microcontroller would have to count if its three then the system has to unlock a deadbolt and if not light a red indicator.
