This issue is ideally suited to including dual tone multi-frequency (DTMF) interpreting on your project. This detection module translates the incoming tone and produces a coded output that can be connected to all way of microcontrollers.
DTMF is typically discovered in touch tone devices along with a telephone. The tone is a mixture of separate sine waves that produce a unique signal that may be transmitted or heard. When the module receives the signal it can decode it and bring a binary output that may be utilized in different devices. The module indicates the nation of the signal thru onboard LEDs.
As an idea, you may join up a mobile smartphone thru 3.5mm to a 3.5mm cable to the module. Dialling into the cellphone from a second mobile after which the use of the keypad will produce the tones on the unique smartphone. The tones inside the name can then be interpreted by means of the module, allowing you to manipulate all way of initiatives. The pins are desirable to conventional sockets with a pin pitch of 2.54mm.
The MT8870 Tone Decoder is a sort of commonly used multi-frequency decode IC product evolved by the MITEL organisation. It is a complete DTMF receiver. After it received the DTMF sign, it's going to divide the sign into high-frequency organization and coffee-frequency institution and send the sign to the digital decoder that can determine out the key cost then send it to the outdoor Bus via four strains( Q1, Q2, Q3, Q4) as the binary form.
Features:
Onboard voice input interface
Low power consumption
Internal gain setting amplifier
Onboard LED, it is very convenient to check the output state.
Adjustable guard time
Central office quality
Onboard 3.5mm input interface
5 Channel interface
On-board MT8870 frequency decoder chip
Power-down mode
Inhibit mode
Onboard audio input interface
Onboard LED lights for output state indication Complete DTMF Receiver.
Does not require external circuits or wiring, it can be inserted directly into the UNO/MEGA2560/DUE board to use.
12-Digital outputs decode mobile and fixed telephone keys (0-9, * #). Also, another 4 Digital output(ABCD) can use “DTMF Dial” for Software control.
