  11. 11. Arduino 最初是針對不會寫程式，也不懂電子學，沒有任何技術背景的學生而設計，他們是 義大利北部伊夫雷亞（Ivrea）互動設計學院（Interaction Design Institute Ivrea） 的學生，身為Arduino計劃共同開發者之一的Massimo Banzi，曾在〈超越兆赫的 人們〉中提到「我們給了這些學生2到4星期的時間，讓他們製作物理運算的物品， 當時，市售的工具幾乎都是以工程師為對象，所以不管是配件或是跳線、接頭的數 量都很多。這對學生來說，似乎太過複雜，使得學生不知道該如何處置。」為了解 決這些問題，於2005年誕生的就是Arduino！ 11
