I am a control engineering student and I am studying the frequency response of a system, so the Laplace domain, the Bode plot, poles, zeros,etc. ... I have clear grasp of their meaning, but if I think about the practice it is hard to grasp, at least for me.
For example, I would like to study the frequency response of a DC motor with Arduino, but really don't know from where to start.
So, how do I study the frequency response of a physical system with Arduino? (for example a DC motor)
