The DTMF Shield for Arduino converts DTMF or Touch Tone signals into a format that microcontrollers or Arduino boards can understand. DTMF tones are analog signals that Arduino and most uC cannot read directly. This module converts those signals into a digital format that uC can easily read.

The DTMF Module is specifically designed to plug right into the Arduino boards, but it can also be used with a variety of microcontrollers.

Here is the functional diagram of the DTMF Shield.

Note: some these videos show an earlier board version with no Arduino headers. The formal version of sale has headers to right into an Arduino board
