In this video we are going to show you how to make an arduino project for home automation to open or close door using arduino.
Open and closed a servo door lock via bluetooth.
Download the bluetooth control app from the play store and install it.
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.
Arduino android based bluetooth control password protected door lock version 2.
Turn on bluetooth in the mobile enter into app if on the door lock will be open.
I published an instructable on arduino android based diy smart lock which can be open and closed using password sent from android smartphone over bluetooth two years back.
You can open or close a lock using your smartphone.
Wiring diagram lets start by wiring the servo to the arduino i would like to note that even though i m using the arduino nano the arduino uno will work just as well.
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.
