I'm really going in circles here. My son and i have been working on a project that uses a DTMF controller to drive relays, from an audio source that uses stereo.
The audio is embedded on to the right audio track,using DTMF Tones For Example the number 1 from the dtmf tone will trigger relay 1 or an assigned relay,And So forth. I am very new to This type of stuff and i also bought the seeedo relay shield thinking this would make it a little easier to do this but i'm at a complete loss. My son was terminal and he has since passed, this project is something that we both started and i intend to make it a reality. can someone please help me with this PLEASE!!! I don't now where to begin with writing code to make this wrk as well!!! Very Respectfully Robert
