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).

DTMF is a common communication term for touch
tone phones.
16 button keypad.

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).
