A Technology for Building Web-Based Laboratories for Teaching Electronics

Abstract

In countries with educative coverage difficulties, it becomes necessary to develop and use new technologies that allow expanding education supply for a larger group of the population. In engineering field, one of the difficulties to fulfill this objective is the high cost of training and practice laboratories. In relation to electronic engineering, a way for having a large number of laboratories could be to develop WEB- based laboratories, available at any time, in such a way that even the less difficult experimental practices could be carried out by students, without physically visiting laboratories. This paper presents the development of a hardware-software system to integrate a basic electronic laboratory on the WEB. This laboratory has a WEB interface that allows carry out experiments using simple electronic circuits, remotely varying its parameters and obtain circuits output signal measures. With the construction of this laboratory prototype, students could carry out practices involving diodes, field effect transistors, bipolar transistors and small signal amplifier. The methodology developed in this work can be easily extended to other types of laboratories and to industrial applications.
