Home automation projects projects sensor transducer detector projects tags. 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. If a piezo speaker hears the right number of. 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.
