DTMF: using your cell phone as remote controller for robots


The PCB layout, for the lazy ones, and the trial using a breadboard.

DTMF_Decoder.png 1st_Test.jpg

The board below is intended to control a soccer video game using as input the DTMF signals of three different cell phones. (note that we are not using the BCD-to-Decimal converters - 74LS47 - here, the outputs of the MT8870 are going to a microcontroller). When the picture was taken only the first decoder was working, the other two had a 1K resistor missing.
