I have done this project before 2 years.
It is very simple.
But sorry to say, I don't have circuit diagram of this.

But its very simple, 4 pins of DTMF decoder goes to microcontroller.
Thats all.


you can go through datasheet of DTMF decoder for rest connection

Let me know if you need any more help.

I guess, since your controlling through mobile,
The mobile will give you DTMF tone via its eraphone out, hence you dont need of DTMF encoder.

Your mail id is unnecessary in a forum post.
How do you like to encode before you decode it. Is it from an encoder or mobile itself?

balwinder124 is silent for a long time, probably he has found the solution, so he is busy on doing it
