So let's look at what happens when you make a tool that anybody can just pick up and build something quickly,
讓我們看看一些實例，有了這樣一個工具，任何人都可以在它的幫助下很快制作想要的東西，
so one of the examples that I like to sort of kick off this discussion is this example of this cat feeder.
先看第一個例子，這是一個給貓咪喂食的容器。
The gentleman who made this project had two cats.
這個設計的主人有兩只貓。
One was sick and the other one was healthy, so he had to make sure they ate the proper food.
其中有一只生病了，所以他必須讓它們分開吃東西。
So he made this thing that recognizes the cat from a chip mounted inside on the collar of the cat,
于是他設計了這個裝置，通過貓咪項圈內安裝的芯片識別貓咪身份，
and opens the door and the cat can eat the food.
然后開門讓貓咪吃東西。
This is made by recycling an old CD player that you can get from an old computer,
這個裝置使用了一張用過的CD播放器，從一臺舊電腦拆下來的，
some cardboard, tape, couple of sensors, a few blinking LEDs, and then suddenly you have a tool.
還有一些紙板、膠帶、幾個傳感器和閃爍的LED顯示屏，就制作好了這樣一個工具。
You build something that you cannot find on the market.
一個市場上買不到的東西。
And I like this phrase: "Scratch your own itch."
有句話說的好：“撓自己的癢”。
If you have an idea, you just go and you make it.
如果有自己的想法，就得動手去實現。
This is the equivalent of sketching on paper done with electronics.
這就像在紙上畫畫一樣，只不過是用電子裝置完成的。
So one of the features that I think is important about our work is that our hardware,
這個項目很重要的一個特點在于硬件，
on top of being made with love in Italy -- as you can see from the back of the circuit -- is that it's open,
當然首先是意大利傾情制造的，從電路的背面可以看到，更重要的是它是開源的，
so we publish all the design files for the circuit online,
我們把所有的設計文件都發布在網上，
so you can download it and you can actually use it to make something, or to modify, to learn.
任何人都可以下載，在指引下進行制作或者改裝，學習。
You know, when I was learning about programming,
我當初學習編程的時候，
I learned by looking at other people's code, or looking at other people's circuits in magazines.
就是通過看其他人的代碼學習的，或看其他人發表在雜志上的電路圖。
And this is a good way to learn, by looking at other people's work.
通過看其他人的作品來學習，這是一種很好的學習方式。
So the different elements of the project are all open, so the hardware is released with a Creative Commons license.
這個項目的各個組件都是開源的，比如硬件就是在“知識共享許可協議”下公開發布的。
So, you know, I like this idea that hardware becomes like a piece of culture that you share and you build upon,
我喜歡這種理念，把硬件作為文化的一部分供大家分享和使用，
like it was a song or a poem with Creative Commons.
就像歌曲或詩歌一樣，只不過擁有“知識共享”認證。
Or, the software is GPL, so it's open-source as well.
另外，軟件通過“通用公共許可”發布，也是開源的。
The documentation and the hands-on teaching methodology is also open-source and released as the Creative Commons.
各種文件和動手教學資源都是開源的，遵循“知識共享許可協議”。
Just the name is protected so that we can make sure that we can tell people what is Arduino and what isn't.
這個協議只對項目的名稱起保護作用，便于我們能告訴大家Arduino到底是什么。
