We learned different ways of combining grasshopper and arduino in design studio this semester. This is an example that accomplishes that idea. Using grasshopper, the user set up an array of openings. He made the openings sensitive to points which are connected to ardunio. The openings have different parameters. So, as the user moves, the arduino senses the movement and moves the openings as a result.
The other project shows how this same idea of parametric design in grasshopper can be constructed in full scale and be responsive to sound using arduino.
It is interesting to see how so many people come up with so many different ideas and interactive tools using arduino. Even though the end result seems complex, all the projects are basically doing the same thing repeatedly.
