DTMF decoder connected to a Cell Phone (Mobile Phone).

DTMF control sequences are sent to the DTMF decoder from the calling phone's keypad, for example 12340* to turn the relay on. The DTMF decoder used in this demo is available from our website: www.cstech.co.uk The 4 pole 2.5mm plug for the Nokia is also available from our website.
