Multi servo motor control via bluetooth using android app arduino and app inventor duration.
To unlock the door.
The servo arm will be connected to the slider lock and will move to 0 degrees to lock the door and 60 degrees to unlock it using commands it gets from out bluetooth device.
Turn on bluetooth in the mobile enter into app if on the door lock will be open.
From here we could add a sensor like a knock sensor so we can unlock our door with a special knock or even a voice recognition system.
After tying in the servo with the latch the servo must be put in a suitable position preferably in the middle of the latch so that the open close motion can be achieved properly.
If you select 90 then the servo will move 90 degrees instead of 180 degrees.
Actually i set two command one is open and another is close and password may contain any digit later or symbol or combination of them as you like.
Note that 180 is the degrees you want to move the servo shaft.
Download the bluetooth control app from the play store and install it.
First of all i tied attach the servo motor to the door lock as shown in the image.
The code for bluetooth control smart door lock is very simple.
In this video you can learn how to make a simple password based door lock system using arduino servo motor and 3 4 matrix.
Before that the function fixes the arduino and elements near the door such that the servo motor s shaft is connected to the door lock.
Compile the code and upload the coding to the arduino.
From here we could add a sensor like a knock sensor so we can unlock our door with a special knock or even a voice recognition system.
Now press on the send button and aha.
