How convert 4 bit D0
D3 from DTMF reciver to DEC. number like" +387xxxxxxxxxxxx"( telefon number) and snd to serial monitor?I dnot have much experience with making code and need some help or suggestionsthank youHi
DTMF gives a particular otuput according to the button pressed on phone, check out his project of mine: https://www.engineersgarage.com/contribution/mobile-controlled-robot. Here you will find a chart which will show you the state of output pins according to the button pressed on phone.
You can easily monitor these output pins through a microcontroller and do the required task.
