Using FFT and Sound Sensor as a switch
hello everybody,
i've searched through ton of posts , haven't found that's used analog sound sensor act switch specific whistle pattern. building project utilize 2 different whistle patterns activate 2 different led's. don't know how utilize fft code in order recognize pattern. have seen plenty of examples of codes recognizing whistle, not pattern. what's missing piece? again, i'm using analog sensor amplifier, still can simple functions b/c don't know introduce/use fft. thanks!

what mean "whistle pattern"?
the fft function tell frequencies @ amplitude present in given short sample of sound. if whistles emit different frequencies, fft might distinguish them.
