The main objective of this project is to unlock a

garage door by a mobile phone using a unique

number entered through the keypad of the phone after

entering the password given to the user .

This project is based on the concept of DTMF (dual

tone multi - frequency).

This DTMF decoder circuit identifies the dial tone

from the telephone line and decodes the key pressed

on the remote telephone.

We used Arduino Uno in our project .

The Arduino Uno is a microcontroller board

based on the ATmega328. It has 14 digital

input/output pins (of which 6 can be used as

PWM outputs).
