Hello, I was just wondering if anyone knows where I can get plans to make a portable DTMF Decoder 
I tried searching and found nothing.. What I would like is that the device that hearing a DTMF tone prints it to a little LCD display. It’s just an idea.. If there anything like that great if not I better start learning and maybe in a year or so I can start working on something.. ;D
