HW#19

Identify the DTMF tones of a cell phone dial buttons. I wasn't going to do this homework assignment, but Mundo had done it using a MATLAB script, so I did mine using MATLAB. There seems to be a problem with the variables going into the script. I can't figure it out but here are pictures of the wiring and the MATLAB script. There seems to be a problem with the MATLAB script outputting to a string variable.

This was a pretty fun assignment because we got to use a microphone and detect the different tones a cellphone uses.
