Temperature-Dependent I–V Characterization of a Diode Using an Arduino Shield Available to Purchase

The Arduino development environment, when combined with basic electrical components, is an effective way to provide students with hands-on learning experiences in the areas of science, technology, engineering, and mathematics (STEM). In this article, the results of the current–voltage (I–V) behavior of an Si commercial diode, in a wide temperature range, using the Arduino board and a Shield made with basic electronic components, based on a methodology that fully automates the acquisition of the experimental data, are reported. The method used, which we have called the Arduino Shield, proved to be an efficient resource, as the I–V characteristic of the diode agreed satisfactorily with the results obtained through the traditional approach using current and voltage meters and an adjustable power supply. The tendency of the I–V curve of the Si diode, in the temperature range and current interval studied, was shown to satisfactorily follow the theoretical mathematical model...
