Hi, I want to read the fundamental frequency at which an object is vibrating. I bought a MEMSIC2125 Acceleration for this purpose but I've been reading on the forums and it says the arduino will only be able to identify frequencies below 50Hz because of a filtering cap. Is this true?
My understanding is that to get frequency I just capture acceleration measurements in the time domain and then use a Fast-Fourier-Transform to find the frequencies, and then just pick out the strongest one.
Is this feasible with an Arduino Uno R3? Or do I need something else?
