fft code for arduino
As the name implies, fast Fourier transform (FFT) is an algorithm that determines the discrete Fourier transform of an input significantly faster than computing it directly.
In computer science lingo, the FFT reduces the number of computations needed for a problem of size N from O(N^2) to O(NlogN) .
