SUMMARY:

The separation between the study of theory and the realization of practical experiments
has always been a challenge in the disciplines of electricity and electronics. Some instruments
used in practical classes that allow the generation and measurement of electrical quantities
are usually expensive to acquire by most students, which restricts their realization to a specific
laboratory of the educational institution and to specific times. This factor also makes it impossible
for students to carry out these practical activities at home, which goes against current teaching
trends, which are semi-presential education and distance education. In view of this reality, the

present work consists of the development of the MiniLab Metrópole, an innovative and low-
cost portable computational solution for practical experiments in electricity and electronics.

The research and construction of this artifact was initially thought for students of the semi-
presential technical course with an emphasis on electronics at the Instituto Metrópole Digital

(IMD). The idea is for the device to be composed of electronic hardware, with a microcontroller
(ESP32) centralizing the execution of actions, commanded by software embedded in a cell
phone (also developed in this project and which will be the control interface by the user).
As characteristics, it is intended to incorporate into the product the main functionalities of a
multimeter, an oscilloscope and a signal generator, which are traditional instruments and widely
used in experiments in this area. MiniLab Metrópole seeks to make it possible for students to
have their own small laboratory for carrying out introductory experiments in subjects involving
electricity and electronics in the course, without necessarily having to wait for the specific
moment of a face-to-face class. Thus, some basic practical activities could be carried out at home.
As it involves the construction of a technological artifact, it was decided to adopt Design Science
Research as an epistemological-methodological approach. Initially, the main functionalities
of the equipment used in electricity and electronics laboratories that have the potential to be
integrated into the project were identified. With this survey, some of the prototype’s functional
modules were developed, while others will be produced in the rest of the research. The next step
is to propose practical activities that can be performed with the device. Finally, the prototype will
be validated through its use in three practical experiments and compared with results obtained
using commercial equipment. It is hoped at the end of the dissertation that the use of this
educational artifact by students in the technical course at IMD can bridge the gap between theory
and practice, resulting in an increase in learning.
