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.
Secret knock door lock arduino.
We use the arduino uno but any standard arduino is appropriate for this project.
Unlike the previous projects instead of hiding a door behind an other object this individual took on the challenge of.
Arduino detecting door lock knock secret protect your secret hideout from intruders with a lock that will only open when it hears the secret knock.
There are many types of security systems available to secure our place.
In the old movies a little sliding door would open so the doorman could check you out and let you in.
Smart knock detecting door lock project using arduino uno.
Unlock the door with a secret knock.
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.

In this project i used an arduino uno a piezo speaker and a servo motor.
Build this project at our next weekend long arduino workshop.
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.
With the help of an arduino these secret doors appear to open on their own.
Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.

All you need to do to activate them is touch the right book or do the super 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 pattern.
This lock will be mounted to a picture frame safe on a wall that will open when the correct amount of knocks are administered.
Security is a major concern in our day to day life and digital locks have become an important part of these security systems.
Press the button to record a knock pattern then test it by knocking.
Stop for a second or two and you ll probably see secret knock failed or door unlocked.
