duplex communication using DTMF tones

hello guys!!!!

As requested bysome of the sun campus ambassadors to have a duplex communication I together with JAI have started working on it and we are surely going to come up with a solution within days.

we have founded a DTMF generator ic which we will interface on the receiving end where the robot car was actually placed and then we are trying to send back the dtmf tones to the caller which wll be indicative of some feedback.

Thereby the overall system will be completely automated from both sides.
observing the interest of the readers in this project i have tried to interface the complete circuit with the AC power supply to completely automate the switch board of my room.

details and the circuit of which will be posted soon.!!!!
