Hi I am a student and I am working with this project. But i can not decode DTMF signal. Because when i cut headphone wire I see that there are three colored wire GOLDEN, BLUE and RED. can not identify the RING and TIP wire. Please Please Please give me some advice or circuit diagram that I can connect RING and TIP to MT8870 DTMF decoder IC. And also actually where I cut the headphone wire after MIC or before the MIC. Please Please Please give me some advice. I want to complete my project. Please mail or contact me: akash.cse.du@gmail.com or shaylakash@ymail.com
hi! plz tell me how can i check that my circuit is generating correct dtmf tone or not? means, what is the voltage level at the output of the cell phone?
hi sir this kamal..can u plzz post me the data about ur project????it'll help me alottt so request you kindly to send it as early as possible...plzzz and also xplaination about how to make cicuit connections plzz.. my email id is kiran_sai1768@yahoo.com
These limits can cope with the use of a mobile phone for robotic control. There is no interruption to the service provider's area of area, other restrictions on interference and twelve regulations. It provides the benefits of strong controls.

nice Project...i did it successfully.
Now trying to make a Spybot with a 3g mobile.
And guys d code is same as given above...
Thanks Amey,
Do share you experience with new project using 3G.
