So let's look at what happens when you make a tool that anybody can just pick up and build something quickly,
so one of the examples that I like to sort of kick off this discussion is this example of this cat feeder.
The gentleman who made this project had two cats.
One was sick and the other one was healthy, so he had to make sure they ate the proper food.
So he made this thing that recognizes the cat from a chip mounted inside on the collar of the cat,
and opens the door and the cat can eat the food.
This is made by recycling an old CD player that you can get from an old computer,
some cardboard, tape, couple of sensors, a few blinking LEDs, and then suddenly you have a tool.
You build something that you cannot find on the market.
And I like this phrase: "Scratch your own itch."
If you have an idea, you just go and you make it.
This is the equivalent of sketching on paper done with electronics.
So one of the features that I think is important about our work is that our hardware,
on top of being made with love in Italy -- as you can see from the back of the circuit -- is that it's open,
so we publish all the design files for the circuit online,
so you can download it and you can actually use it to make something, or to modify, to learn.
You know, when I was learning about programming,
I learned by looking at other people's code, or looking at other people's circuits in magazines.
And this is a good way to learn, by looking at other people's work.
So the different elements of the project are all open, so the hardware is released with a Creative Commons license.
So, you know, I like this idea that hardware becomes like a piece of culture that you share and you build upon,
like it was a song or a poem with Creative Commons.
Or, the software is GPL, so it's open-source as well.
The documentation and the hands-on teaching methodology is also open-source and released as the Creative Commons.
Just the name is protected so that we can make sure that we can tell people what is Arduino and what isn't.
