WebDec 2, 2024 · The Nyquist-Shannon Sampling Theorem tells us that to be able to sample a signal, the sampling frequency needs to be at least twice the frequency of the signal we’re trying to sample. In other words, the FFT will only be able to detect frequencies up to half the sampling frequency. On a common Arduino, the sampling frequency is quite limited ...

WebJul 25, 2024 · An FFT lets you decompose a sequence of samples into components of different frequencies, usually into "buckets" that each have a small frequency band. You can then have a look at these buckets to see if there is a peak in a specific frequency range. There are several examples and libraries for this on Arduinos, like EasyFFT and … WebThe original EasyFFT function designed to have up to 1028 samples (with the compatible board), while we only need 128 samples. this code reduces memory consumption of around 20% compared to original EasyFFT function. Once FFT is done, the code returns the top 5 most dominant frequency peaks for further analysis. This frequency are arranged in ... Webeasyfft.
