It was a great opportunity provided by Penn State Postoc Society, that both me and Sasmita were able to present a few projects at ExplorationU @ Mount Nittany Middle School. We presented 3 projects that involved light sensors doing some amazing things, particularly a color sensor detecting colors, a gesture detector sensing hand movements and a proximity sensor to look at the distance of hand from sensor. The joy that kids got from interacting with these sensors made our day!
