Secret Knock Detecting Door Locker

Abstract

The Project idea was to build a knock detecting door locker which can identify the specific knocking pattern and unlock the door if the pattern is correct. This door locking system provides much security than systems which are currently using. When there are many users who use the door, error may occur because there is only one key to open the door. But here in this door locking system this kind of errors may not occur because the users who know the knocking pattern can open the door any time without a key.
