Abstract
Creativity plays a vital role in development of any product, process or a system. Expansion of an
idea is one of the basic steps in this regard.
In this project, we present controlling of a car using DTMF technique. The car is controlled by a
mobile phone that makes call to the other mobile phone attached to the car. In the course of the
call, if any button is pressed, tone corresponding to the button pressed is decoded at the other end
of the call depending upon the generated signal. This tone is called dual tone multi frequency
tone (DTMF).
Using DTMF code, direction of motion of the car can be controlled by mobile phone. Car has a
wireless camera that transmits an actual video at the operator's monitor. Based on the received
video, the corresponding signals from the mobile phone keypad can be passed from the mobile
phone which is connected with the transmitter side.
