DTMF Based Door Open And Close

DOWNLOAD ABSTRACT

AIM:

Design and Development of DTMF based door open and close.

PURPOSE:

Regular doors and windows are operated manually. Locking and unlocking done through manual keys. This required manual operation. Few kind of industries have so many doors in different premises. It is very expensive to provide manual operation in everywhere. Convert them into automation can provide easiness. Here we are doing DTMF based door open and close using Arduino. It can provide door operation from remote place.

DESCRIPTION:

This project includes DTMF module (CM8870), which is connected to Arduino digital pins. Sliding door controlled by l293d which is connected to Arduino digital pins.

WORKING:

In this project we can open and close door using DTMF. Here mobile connected to DTMF mobile through audio cable. User need to do call from another mobile to DTMF connected to mobile. After answering call user can control from remote mobile by pressing keys. Door open close status will display on 16X2 LCD display.
