As part of the course, we made an automated air freshener for one of the bathrooms at the university. By using an old R2-D2 plastic candy jar, we decided to try to see if they could make the Intelligent Toilet Ambience Star Wars themed. We loaded up the R2-D2 shell with an Arduino, a ton of sensors and an actuator for triggering the air freshener. An additional assignment involved using OpenCV to recognize hand gestures. A video in Dutch that explains this can be found at the bottom of the page.
