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.
Secret door lock arduino.
With ismailsan s electronic lock the secret knock automatically unlocks the door.
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.
First of all we start from the brain of this project which is the arduino uno board.
Add an h bridge to the circuit so it can lock and unlock the door.
The aim is to control a door lock without keys but using a smart phone instead.
Unlock the door with a secret knock.

Some examples are pir based security system rfid based security system digital lock system bio matrix systems electronics code lock.
You can see a video of how it works below.
Using the code posted i was able to re use the secret knock detection algorithm without having to create one on my own.
This is a simple project made with arduino uno r3.

The servo motor is used to push lock or pull unlock the latch on the door.
If a piezo speaker hears the right number of.
Use a servo to unlock the door rather than this hacked together gear motor slip transmission.
This is the changes that i ve made added a hall effect sensor to determine if the door is open or closed swapped the gear motor with a servo added a serial lcd feedback screen added a yellow led added a bunch of extra features.
Take a multimeter and test the conductivity of metal parts going through the door.

The arduino board is connected to an lcd and a servo motor.

In this project i used an arduino uno a piezo speaker and a servo motor.
Hi all i ve done a bunch of modifications to steve hoefer s code for his secret knock detecting door lock.
The complete circuit diagram for our arduino based digital keypad door lock project is shown below.
The project uses a stepper motor and stepper driver to open the door and a capacitive sensor to sense taps on the peephole.
