LDR vs Luz

We aim to develop realistic simulators in three dimensions based on remotely controlled experiments, aiming to promote the teaching and learning of Physics, Science and programming. Currently there are some similar didactic tools, however their graphic and interactional levels are not following the technological development.

With the aim of winning over young audiences, providing interactive, current and related content, the process was divided into idealization of the experiment, pedagogical planning, creation of the real experiment, graphic modeling of all components, programming, connection between the physical event and the simulated and available online.

In the process, several software were used, which were chosen using the guideline of maximizing the graphic quality and minimizing the production cost. Making it possible for any researcher to replicate the development methods in the future, therefore the software, initially chosen, underwent modification as the research deepened, as well as the accumulation of new possibilities of technologies such as Virtual Reality VR and Augmented Reality AIR.

Partial results were obtained with the development of an augmented reality application, which studies the operation of a common electric motor, virtually replicating all the existing components inside it, and allowing the user to freely view it from all angles, from different distances and with rotation accelerator, its link is available inside this app.

Just as a replica of the real experiment has been recreated using Virtual Reality, providing a highly immersive and interactive environment available for Meta Quest 2.

In summary, the Android application and the VR simulate the experiment that consists of reading the light intensity by a photoresistor (LDR), this data is interpreted by the Arduino, which in turn is controlled by the Raspberry, where the other calculations are performed, passing on to a web page the result, giving the end user the opportunity to control a physical experiment remotely.

This App is part of the master's project Use of digital technologies applied to Project-Based Learning for teaching radiation propagation.
