sir, i have taken this up as my b.e project.
i am not using a cellphone as a dtmf input.. instead, i plan to use the dtmf encoder ic um91214.. but the problem is that the cost of this ic is around 1100rs which is not quite affordable for me.. so can you suggest any other affordable optional dtmf encoder ic..?
waiting for your reply..!
