Albero di(Gi) Natale is my first project made using Arduino. "Albero di Natale" means Christmas Tree in Italian. So the name has been created by the combination between "Albero digitale" and "Albero di Natale" and can be write down in both forms: Albero digi(Na)tale or Albero di(Gi) Natale.
It is a small object (27cm x 23cm x 32cm): a sculpture, made of recycled materials (CD, copper and plastic pipes, electric cables, wood), equipped with LEDs controlled by Arduino. It is aimed at evoking the shape of a strange "exotic" tree decorated by Christmas decorations. It is a work in progress started in the fall of 2012 that currently has reached its final stage for the visual aspect. Arduino controls the lighting and the power off of the LEDs through a program that, in order to generate perceptually a periodic sequences, uses prime numbers for the computation of pulse lights intervals.
