I worked for Eva Durall for a research project and created these 3 boxes that are connected to each other through infrared light. They only can send information to each other and activate when snapped together with the magnets that are attached on each side. The last one has a memory game on it. Arduino code and electronics by me. The software was coded by Regis Barreto Frias and Juaquin Aldunate.
