4.  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).

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

13.  The frequencies generated on pressing different keys
are shown in the table:

941 Hz * 0 #

14.  This DTMF decoder circuit identifies the dial tone
from the telephone line and decodes the key pressed
on the remote telephone.

19. 1. A SIM card must be inserted in the
phone.
2. Automatic answering mode must be
selected.

21.  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).
