ECE Project on Device Control using Telephone

This is Electronics final year project report on device control using telephone. This system uses Dual Tone Multi Frequency (DTMF) technology of our telephone set. Every telephone set will have this facility. We have two type of dialing facilities in our telephone system (i) Pulse dialing mode (ii) Tone dialing mode. Here this system works on tone dialing mode. The DTMF mode is shortly called as tone dialing mode. This circuit does not require any complex IC, so any one with little knowledge of electronics can construct this circuit, because it does not need any programmable IC's or programming. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.
