The electronic system made it possible to monitor a movement with characteristics similar to those of a simple harmonic motion, through a looping device, allowing the demonstration of the law of conservation of energy. The monitoring of the experimental configuration was carried out using the Arduino® platform. Demonstrations involving the use of the apparatus as well as the video analysis software were made for Physics students from a high school. The results showed that the automation of a simple experiment can become an interesting tool for both the teaching and learning process, triggering social interactions among students useful to assist in the fixation of physical concepts, even the most abstract ones such as Energy. In addition, the use of video analysis software provides students with experiences of collecting data, analyzing graphs and tables, which supplements the understanding of the nature of science and scientific practice. Keywords: educational robotics, physics experiments, Arduino® projects 1. INTRODUCTION Education is the backbone of any developing society and improving its quality is a key factor that defines advancement in a world parameterized by science and technology. Educational researches, especially those aimed at teaching Science, has dedicated special attention to the innovation of methodologies that contribute not only to allow a greater understanding of the concepts by students, but also provides the means to develop skills and competences useful to the exercise of citizenship. In this direction, many researches have drawn attention to the use of so-called digital technologies of “Information and Communication”, as well as robotic platforms in the teaching of Physics and Science in general. It should be noted, in this context, that Physics is a vast field of study involving several theories and concepts that can be represented mathematically and demonstrated through practical experiments. The teaching of Physics in general begins in primary schools and is a matter of great importance. Thus, it is necessary to ensure that it is developed in the best possible way to enhance students' understanding of real-world phenomena. However, concepts built within Physics to study natural phenomena are extremely abstract and therefore bring many difficulties for students' learning. In relation to this point, the concept of Energy stands out, which, in addition to being very abstract, is of great importance for understanding many phenomena. Therefore, the use of experiments can be
