I'm a newbie, looking to build a simple, small and cheap appliance that will receive data input via serial port and then generate DTMF tones through a speaker...the DTMF tones will basically be characterizing the data received, in some sense.
From what I've read, arduino seems well-suited for my project, right?
My question is this -- does anyone have recommendations for the lowest cost hardware that I could use to perform the DTMF tone generation? (Note: DTMF detection is NOT required).
Thanks in advance
