    Presentation (PPT) : Introduction

    Backbone of This Project:

    Microcontroller

    c++

    DTMF

     

    About DTMF:

    It First invented in Bell Laboratory. 

    It Refers to dual tone multiple frequency signal.

    In this two frequency work together.

    It can be seen in mobile phone.
