For my final project I need to measure vibration using arduino with piezoelectric sensor.I need to find the frequency of the sensor values.I prepared a model like in the picture but all scopes give the same values.Is it supposed to be like this or did I make a mistake?![fftresim.PNG](https://www.mathworks.com/matlabcentral/answers/uploaded_files/226339/fftresim.png)
