In view of the difficulties encountered in science teaching, specifically in the teaching of physics, studies aim to develop methodologies that help science teaching. In this context, the present work proposes the use of the Arduino platform as a methodological tool to improve the teaching of physics in high school... For this purpose, the objective of the work was to produce physics experiments with the aid of Arduino that can be used in the classroom and thus we investigated that the experiments provided students with a dynamic and close to ideal class in physics teaching. For the development of the research, two experiments were presented, in the areas of thermology and optics, for students of the second grade of high school from two public schools in the city of Picos (PI). After the development of the experimental activity, a simple questionnaire was applied that aimed to support whether the experiments used with Arduino contributed to the teaching of physics. The results obtained were discussed based on the questionnaire applied, indicating that the experiments produced with Arduino contributed significantly to teaching physics learning, indicating that it is an excellent methodological tool for teaching physics and science in general (read more)
