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.
