I know how irritating doorbell sounds whenever it rings we have to hold our work and getup to open the door. Because of this problem, I decided to make my own Automatic Door Lock System.
In this video step by step, the procedure is shown how I made my door lock system.
I made it with the help of all the items available in the home. I had not single rupees to make it. Hope you will like it.
