This work consists of the development of teaching didactic prototypes using the Arduino
electronic prototyping platform, aiming to assist in the teaching and learning of the
Electromagnetic Theory subject, offered in the Computer Engineering course at the
Federal University of Par ́a (UFPA), Castanhal campus. These prototypes were built
with low cost material. The use of Arduino in the development of these prototypes is
of fundamental importance as an interface for measurements and analysis of physical
quantities, such as: the electromagnetic field, the induced current and the voltage acting
on the system. Five teaching didactic prototypes were developed: the Oersted experiment,
a simple motor, an electromagnetic generator, electromagnets, and a mini Tesla coil.
To obtain the results, specific commercial sensors were used for each magnitude in the
proposed experiment. In addition, the development of programmable code in the Arduino
integrated development environment (IDE) was carried out to enable the exposure of the
measurement results of the parameters under analysis. In this way, it became possible to
generate graphs and visualize the quantitative results measured by the sensors, through a
liquid crystal display (LCD). The development of experiments as pedagogical activities was
motivated by Novak’s humanist ideals and Marcos Antˆonio Moreira’s vision of meaningful
learning. According to these educators, the effectiveness of technological tools for teaching
and learning are excellent methodologies to be addressed in the classroom.
