The Facade has being concieved as a rigid surface with openings. Every period in history is represented by different typologies/configurations that can be recognised and categorised. Nowadays we live in an interactive world our buildings cannot stay rigid, they should be responsive to different environments.

Applying the same strategy to our facade we can achieve responsiveness. The facade reads the inputs and create “gestures” that perform a function. So the facade can be triggered by the amount of light, the human proximity, the need for ventilation or the sound in its surroundings, and just as a nervous system works, transform those stimules in motion functio

Concept
Building gestures
Facade “gestures” allow buildings to react to the stimulus of the environment.

The purpose of this exercise was to control a servo motor with a digitalWrite input. We  created a led sequence in one arduino and a light sensor connected to the servo in an another arduino board. The amount of  light that the sensor detects triggers the speed and the rotation of the servo. Using two different arduino boards helped us to experiment the distance between the light sensor and the leds which allowed us to have a wider range of servo outputs.
