Didactic tool for practical testing of digital voltage grading applications

What is it about?

This paper describes the construction, programming and implementation of an educational embedded system made up of free educational software and an embedded control of sinusoidal alternating voltage for electricity practices in power electronics laboratory. Thus, this work presents educational software developed and applied to digital control, wirelessly via Bluetooth, to change the AC voltage of the grid using Android smartphones or tablets, making the experiment more interactive and playful. The application of educational software in experiments also allows verifying the program change influence in physical phenomena and stimulates the logical reasoning development and consequently the autonomy of the students that can raise hypotheses, make interferences in the programming and drawing conclusions from the practical results obtained.
