Connect this with your cell phones earphone jack (3.5mm), dial your number from another cell phone and press any keys. Those keys will be decoded to 4 bit values on the DTMF decoder module connected on first cell phone. This module can be used to make mobile operated robots and other mobile operated gadgets.
