Experimentation with LED light

There are many tutorials how to make a heart beat monitor with arduino, basically the sensible area of the scheme reacts to every beat that creates waves. Although in this case because of need of pressure the projection provides inaccurate beat.

This project seems interesting as well, the principal is that each wire has a sound programmed through laptop.The peculiar part is how system is adapted using cans, because tabs are really sensitive to touch when turned to right angle. Even if this isn't new system but the fact that it can be made at home makes technology somewhat more reachable.

Arduino is electronics platform to make interactive projects combining software and hardware.
Quite a lot of interactive technologies have the same base as Arduino. So it's used to create something outside your computer screen.
