Block programming to develop interactive activities in the analysis of passive filters using an RC circuit for distance classes

Abstract

Block programming was developed for interactive activities in the analysis of a passive low pass filter using a RC circuit for distance classes. On a breadboard, was integrated an Arduino development board, a potentiometer and a visual indicator (a light emitting diode LED). The development of the programming was carried out using the software LabVIEW to generate an interactive front panel that allows us to manipulate and visualize the calculations, the graphic expressions and at the same time vary at least one passive element. A graphical interface was obtained that allows iterations and immediate calculations for the missing parameters to see the behavior of the filter and also generates a display for the mathematical expression and its Bode plot, the resistance allows us vary the values and make a sweep to locate the angular frequency and activate the light emitting diode connected on the development board. In the programming a web camera was implemented to visualize the circuit in real time at the moment of manipulating a graphical interface.
