Resumo(s)
In the past few years, the technologic evolution of
communication and information systems had a major impact in
our lives. In education, this evolution broke some geographical
barriers, facilitating students’ access to real laboratories using a
simple device connected to the Internet, contributing therefore
to improve teaching and learning methods. To support this
evolution, this paper describes a remote laboratory that
provides students’ access to a typical electronic instrumentation
system. Through a set of webpages, users can remotely control
a light intensity sensed through a Light Dependent Resistor
(LDR) sensor connected in an arm of a configurable Wheatstone
Bridge (WB), whose output differential voltage are amplified /
attenuated by an Instrumentation Amplifier (IA) circuit.
Through this laboratory, users are able to control several
components of a typical instrumentation system, visualize
changes and analyze some measurements, in the same way as
they would do in a traditional hands-on laboratory. An overview
of the developed remote laboratory and a contextualization
within other available solutions are presented in this paper. At
the end, some considerations for its adoption in education are
described.
