Arduino Tilt Sensor Motor

Team: Lisa Li, Leah Ling, Willow Hong

We began choosing the thermistor as our input. After changing lot of the codes and then running it, we found that the thermistor was not sensitive enough: there were not enough variance the printed data. We actually wanted a input that would give more distinct raw data; therefore, we changed the input to a tilt sensor.

We started with a speaker as an output. But we soon found that firmata did not work with speaker. So we moved onto a motor.

System function: tilting the tilt sensor in different directions (from -90 degree to 90 degree) changes the speed in which the motor vibrates.

Stella Artois: Give Beautifully

This interactive light installation was designed by UNIT9 for Stella Artois’ global Christmas campaign ‘Give Beautifully’. It was released December of 2015. The concept was to create a space that gave city dwellers a canopy of stars that they otherwise would not be able to experience due to the mass amount of lights in the city during the night.


The installation is 20m x 20m and consists of clusters of interactive and kinetic stars. The floor is made of glass so the stars can reflect off of it and double the impact of the stars: creating a sense of infinite amount of stars.

There were three types of stars that differed in sizes and functionality: largest ones were kinetic globes; small static globes; and a cloth dotted with hundreds of LEDs stars. When the audience raised their arms towards the sky, the movement triggers the large stars to descend down towards them.

Five of the large kinetic stars were extra special. When the audience reaches for one of those particular stars, they flash white and a hidden camera captures a picture of the people reaching up from below.


The Event of a Thread

This installation by Ann Hamilton was shown at the Park Avenue Armory in New York. The center piece of this installation involves 42 swings hung from the ceiling. The swings are divided into two fields by a large white curtain that bisects a 55,000 sq.ft. hall.  The swings are connected to each other and the curtain via ropes and pulleys. A visitor’s momentum on the swing  activates a rolling undulation of the curtain. The two fields of swings mirror each other so when corresponding swings are moving at the same time, the undulation of the curtain is enhanced.
