Interactive architectural component

This project examines architectural components and integrated physical computing technology. The piece is both digitally designed and fabricated, as well as manually worked and constructed. The form has a plywood solid base, to enclose the circuitry and microcontroller. There is an acrylic LED holster, and an acrylic tube to encapsulate the light. As a viewer approaches the object, an ultrasonic sensor picks up the distance from a viewer to the object, and adjusts the lights to the distance, becoming brighter as a person gets closer. When there is no presence within the range of the sensor, the object enters a ‘sleep state’ and breathes dim light.
