-  In this example, the Arduino simulates the sampling of a sinusoidal 1000 Hz
-  signal with an amplitude of 100, sampled at 5000 Hz. Samples are stored
-  inside the vReal array. The samples are windowed according to Hamming
-  function. The FFT is computed using the windowed samples. Then the magnitudes
-  of each of the frequencies that compose the signal are calculated. Finally,
-  the frequency spectrum magnitudes are printed. If you use the Arduino IDE
-  serial plotter, you will see a single spike corresponding to the 1000 Hz
-  frecuency.
