摘要：This paper describes the construction, programming and implementation of an embedded system based on free educational software and an embedded control of sinusoidal alternating voltage (AC) for electricity practices in Physics laboratory. Software can be considered educational when properly contextualized in a relationship of teaching and learning. 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 to verify, in real time, the influence of programs change on the physical phenomena and stimulates the logical reasoning development and consequently the autonomy of the students, to the measure that can raise hypotheses, make interferences in the programming and take off conclusions from the practical results obtained.
