I want to connect a cell phone to arduino using DTMF decoder or transceiver and control the arduino remotely from another phone. Which DTMF decoder chip works well and is easy to operate like using serial or 12C or something? I am planning to buy some parts from this website. Will any of the I.Cs on this site work.
The link is http://www.onlinetps.com/shop/index.php?main_page=advanced_search_result&search_in_description=1&keyword=dtmf .
Also can a transceiver both send and decode DTMF signals?
Will the MT8870 or MT8880 work. How do they communicate with arduino.
Thanks in advance.
