Arduino Your Home Environment: Producing DTMF Tones

In this project we will develop a tone generator using Arduino Uno. . We will have buttons interfaced with the UNO and each one of them generates different intensity of tone. The frequency of tone generated by the UNO is same at every internal.

Arduino Playground - DTMF

Dual Tone Multi-Frequency (DTMF) is generally used for telephony application. In the case when the MCU does not carry a DTMF generator, a software implementation can be achieved by using the Pulse Width Modulation (PWM) module of the MCU.
