I am a 2nd year b.tech student.
I want details about this topic as I am planning to do it as my miniproject..
I had submitted my abstract..I prefer to use landphone for the same..
This should employ DTMF technique to switch on/off up to nine appliances
(corresponding to the digits 1 through 9 of the telephone keypad). This can be done even during normal conversation...
Also a microcontroller to know present status(whether working or not)..
Can anyone help me please?
