Instrumentação eletrônica com o arduino aplicada ao ensino de física

Abstract

In this work we study the application of microcontrollers like Arduino in electronic instrumentation, focusing special attention in Physics Teaching. We have proposed some didactical experiments involving thermal sensors, thermodynamics (appendices A and B), and a linear Hall effect sensor to measure magnetic fields (appendices C), aiming to measure and collect physical parameters and to control physics experiments in didactic laboratories. We have produced some electronic experimentation scripts and useful support material, destined for teachers of science of elementary and high school, as well as useful for undergraduate students of degree courses and bachelor's degree in physics. The experimental apparatus proposed in this work plays a key role to obtain abstract physical knowledge as: temperature, heat, and thermodynamic in general, in which the combination of basic theory of data acquisition with the experimental practice makes such concepts most relevant and contextualized for students and teachers. The possibility of inclusion of the computer and electronic instrumentation in classroom can be a strong ally of the teacher, contributing to increase the interest of students and teachers in the use of new technologies in the classroom, in order to improve and make more meaningful the learning of physics for all involved.
