This research project explores the Arduino potentialities, as a performer and mediator between individuals and their environment. Our goal is to generate spaces to modify that environment through an interface that dialogues with stimuli and actions.Our interest is to connect vulnerable individuals to possible acts of appropriation that is, being able to perform a symbolic ownership of their environments. For doing that, we see the opportunity of using Arduino within the context of differential pedagogy for children with special needs. All this, considering the evident deficiencies of that kind of educational facilities, particularly regarding children with motor disabilities daily activities.
