Embedded System for Real Color Composition in Experimental Physics

Software can be considered educational when properly contextualized in a relationship of teaching and learning. This paper describes an embedded system and an educational software developed and applied in experimental physics to real and virtual colors composition. The educational system developed allows student interaction by voice commands, which makes the assimilation process of red/green/blue (RGB) color formation concepts more didactic 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 hypothesis, make modifications in the programming and take off conclusions from the practical results obtained.

Online Monitoring System for Electrical Microgeneration via Embedded WiFi Modem

The present project consists of a system based on free hardware and software for online monitoring, using a Wi-Fi embedded modem, applied to an electrical microgeneration plant based on thermoelectric microgenerators (GTEs). These have small size, zero-carbon emission, no moving parts or noise and produce electricity through the reuse of waste heat. The main objective is to analyze plant variables through online monitoring software developed in order to allow data storage in an online database and chart generation with the possibility of remote access.

Didactic tool for practical testing of digital voltage grading applications

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.
