Lay out and test the.
Knock pattern door lock.
Now after saving the input pattern press and immediately released the push button for taking input from the sensor to arduino to open the lock.
Secret knock detecting door lock step 1.
The idea is pretty simple knock in a certain pattern and the door unlocks.
After six times knock arduino find the knock pattern and save that in eeprom.
Now we have to knock 6 times.
Knock knock pause knock the knocklock then activates an internal relay that can switch power to a lock mechanism such as an electric door strike electric car door lock or electric garage door opener for example.

Now we have to knock 6 times.
We ve seen itbefore several times.
After six times knock arduino find the knock pattern and save that in eeprom.
After it arduino decodes it and compares with saved pattern.
This solution is somewhat cleaner than the others not only in physical design but.
This section assumes that you know how to connect your arduino microcontroller to you.
This project will take several hours to complete.
Now after saving the input pattern press and immediately released the push button for taking input from the sensor to arduino to open the lock.
