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.
DTMF :
16 button keypad.

DTMF Decoder: 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).
