Recover Data with Pure Data

Hello,

I have a sound sensor and I analyze the Data through my code, with the FFT library bellow:

Now, I would like to recover these Data. So I use

Serial.write(fft_log_out, 128)

and followed a Tuto, downloaded Pure Data and the arduino-test.pd but I am unable to set the pins of the COM to receive the right Data.

Is it the easiest way to perform this?

Thank you in advance.
