Secret knock detecting door lock.
A box or door when you provide the correct secret knock.
In this post let us build a secret knock detecting door lock using arduino which can detect the pattern of your knocks at the door and will only open the lock if the knocking pattern matches with the correct.
For the complete project with circuit diagram and code visit.
Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
Abstractthe project idea was to build a knock detecting in building knock detecting door lock we useddoor lock which can identify the specific knocking micro controllers pattern detecting algorithms pattern and unlock the door if the pattern is touch sensor circuit and password detect system correct.

Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock.
Stop for a second or two and you ll probably see secret knock failed or door unlocked.
This started out as a bit of a joke project but turned out to be surprisingly accurate at judging knocks.
So far we ve been using a piezo buzzer only to make noise but we can also use it as a sensor to detect sounds in this case knocks.
Arduino secret door knock unlocker duration.
Protect your secret hideout from intruders with a lock that will only open when it hears the secret knock.
When a piezo is struck it rings like a bell but instead of producing sound it outputs voltage which generates a number depending on the force.
This started out as a bit of a joke project but turned out to be surprisingly accurate at judging knocks.
