Arduino FFT Library Notes: For a faster frequency analysis library, check out the FHT! The serial output of the examples is in binary, not ASCII. This means it will not be human readable on the serial port. Change serial.write() to serial.print() to fix this. You may need to writ...

About the Arduino FHT Library The Fast Hartley Transform (FHT) is a function that converts time domain signals to the frequency domain. This is exactly what the more well known FFT does, but it is specifically designed for real data, whereas the FFT operates on complex data. As a result,...
