Light cubes
Step 4: Electronics
If you want to add the described interactivity
to the cubes you have to integrate infra-red
leds and optical sensors. This is the reason
why I placed the part in the middle a little bit more
inside. This way it can always receive his own infrared
light and so now that it stands next to something.
Arduino is a very good solution for designer which do not have much experience with
programming. You can connect the LED's and optical sensors to the bord
and receive the data. This way you can see which of the 4 optical sensors (left right bottom top)
gets a signal. With this data you can influence the color of a LED for example.
I only implented this in one cube. For the other cubes I
used one LED, a switch and a battery. To prevent from looking directly into the LED (which makes it ugly)
I placed half a sphere on top of it.
