Studies are currently being developed on science teaching for people with visual functional diversity, however, there are still shortcomings in the design of adequate and accessible methods and instruments for teachers who must assume this role. To address this problem, an arduino-based communication interface was designed for the development of an illustrative experiment that shows the occurrence of the thermalization phenomenon. Therefore, we worked with students who present this diversity in different sessions of approximately two hours each to collect data. The research was qualitative to analyze the potential offered by the interface in a regular classroom that presents inclusion of visual functional diversity. For data collection, an observation grid was used to identify the usefulness that the interface can provide.
