In this project i used an arduino uno a piezo speaker and a servo motor.
Secret knock door lock arduino.
Press the button to record a knock pattern then test it by knocking.
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 pattern.
In the old movies a little sliding door would open so the doorman could check you out and let you in.
Stop for a second or two and you ll probably see secret knock failed or door unlocked.
Build this project at our next weekend long arduino workshop.
With the arduino powered on you should see the text program start tap the piezo speaker and you should see the text knock starting and knock each time you tap it.
All you need to do to activate them is touch the right book or do the super secret knock.
Unlock the door with a secret knock.
Smart knock detecting door lock project using arduino uno.
All of the technology and arduino format and code are almost exactly the same as the code from lilgfergi s knock lock but the difference is in the application.
Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
With ismailsan s electronic lock the secret knock automatically unlocks the door.
Unlike the previous projects instead of hiding a door behind an other object this individual took on the challenge of.
We use the arduino uno but any standard arduino is appropriate for this project.

Security is a major concern in our day to day life and digital locks have become an important part of these security systems.

This lock will be mounted to a picture frame safe on a wall that will open when the correct amount of knocks are administered.
With the help of an arduino these secret doors appear to open on their own.

The secret door knocker uses a piezo element to record and detect your secret knock pattern then turns a servo motor that you can connect to your door lock.
There are many types of security systems available to secure our place.
