• Abstract: Frequency response methods are of fundamental importance for dynamical systems analysis. Bode diagrams, in particular, consist of a graphical method of representing the frequency response of systems which can be used for the design and analysis of electrical filters, control systems, communication systems, etc. In this context, this article presents the development of an equipment (Bode Plotter) based on the Arduino platform and aided by a computer, which has a graphical user interface (in Python) to view the Bode magnitude diagram of real dynamical systems. The structure and development of the Bode Plotter, as well as experimental results performed in two test systems are presented to validate the project proposal.
