What is arduino ?

Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online. You can tell your board what to do by sending a set of instructions to the microcontroller on the board. To do so you use the Arduino programming language (based on Wiring), and the Arduino Software (IDE), based on Processing.

Over the years Arduino has been the brain of thousands of projects, from everyday objects to complex scientific instruments. A worldwide community of makers - students, hobbyists, artists, programmers, and professionals - has gathered around this open-source platform, their contributions have added up to an incredible amount of accessible knowledge that can be of great help to novices and experts alike.

 All Arduino boards are completely open-source, empowering users to build them independently and eventually adapt them to their particular needs. The software, too, is open-source, and it is growing through the contributions of users worldwide.

Why Arduino?

Thanks to its simple and accessible user experience, Arduino has been used in thousands of different projects and applications. The Arduino software is easy-to-use for beginners, yet flexible enough for advanced users. It runs on Mac, Windows, and Linux. Teachers and students use it to build low cost scientific instruments, to prove chemistry and physics principles, or to get started with programming and robotics. Designers and architects build interactive prototypes, musicians and artists use it for installations and to experiment with new musical instruments. Makers, of course, use it to build many of the projects exhibited at the Maker Faire, for example. Arduino is a key tool to learn new things. Anyone - children, hobbyists, artists, programmers - can start tinkering just following the step by step instructions of a kit, or sharing ideas online with other members of the Arduino community.

There are many other microcontrollers and microcontroller platforms available for physical computing. Parallax Basic Stamp, Netmedia's BX-24, Phidgets, MIT's Handyboard, and many others offer similar functionality. All of these tools take the messy details of microcontroller programming and wrap it up in an easy-to-use package. Arduino also simplifies the process of working with microcontrollers, but it offers some advantage for teachers, students, and interested amateurs over other systems:

Inexpensive - Arduino boards are relatively inexpensive compared to other microcontroller platforms. The least expensive version of the Arduino module can be assembled by hand, and even the pre-assembled Arduino modules cost less than $50

Cross-platform - The Arduino Software (IDE) runs on Windows, Macintosh OSX, and Linux operating systems. Most microcontroller systems are limited to Windows.

Simple, clear programming environment - The Arduino Software (IDE) is easy-to-use for beginners, yet flexible enough for advanced users to take advantage of as well. For teachers, it's conveniently based on the Processing programming environment, so students learning to program in that environment will be familiar with how the Arduino IDE works.

Open source and extensible software - The Arduino software is published as open source tools, available for extension by experienced programmers. The language can be expanded through C++ libraries, and people wanting to understand the technical details can make the leap from Arduino to the AVR C programming language on which it's based. Similarly, you can add AVR-C code directly into your Arduino programs if you want to.

什么是Arduino的？

Arduino是基于易于使用的硬件和软件的开源电子平台。 Arduino的板是能够读取输入 - 上的传感器，按钮上手指或Twitter信息光 - 并把它变成一个输出 - 致动的电动机，开启的LED，出版的东西线上。你可以告诉你的是什么板子通过发送一组指令到电路板上的微控制器做。为此，您使用的Arduino编程语言（基于布线）和Arduino的软件（IDE）的基础上处理。

多年来Arduino的一直是数以千计的项目大脑，从日常用品到复杂的科学仪器。学生，业余爱好者，艺术家，程序员和专业人士 -   - 厂商的全球社区已经解决这个开源平台聚集，它们的贡献加起来获取的知识数量惊人的，可以是对新手和专家的一致好评很大的帮助。

 所有的Arduino板是完全开放源代码，使用户能够独立建造它们，并最终使其适应他们的特殊需求。该软件，也同样是开源的，并且它是通过用户的不断增长的贡献全世界。

为什么Arduino的？

由于它的简单和方便的用户体验，Arduino的已在数千种不同的项目和应用程序的使用。 Arduino的软件易于使用的初学者，但不够灵活的高级用户。它运行在Mac，Windows和Linux。老师和学生们用它来建立低成本的科学仪器，来证明化学和物理原理，或开始使用编程和机器人。设计师和建筑师建立互动的原型，音乐家和艺术家用它来安装和使用新的乐器进行实验。庄家，当然，用它来构建许多人在制作马戏团展出的项目，例如。 Arduino是学习新事物的关键工具。任何人 - 孩子，爱好者，艺术家，程序员 - 可以开始修修补补只需按照一步试剂盒的操作说明，或与Arduino的社区的其他成员共享网上的想法。

还有许多其他的微控制器和可用于物理计算微控制器平台。视差基本邮票，NETMEDIA的BX-24，Phidg​​ets的，麻省理工学院的Handyboard，和许多其他提供类似的功能。所有这些工具都需要单片机编程的繁琐的细节，并以易于使用的包装包起来。 Arduino的还简化了与微控制器工作的过程，但它提供了一些优势，为教师，学生，以及比其他系统有兴趣的爱好者：

便宜 - 相比其他微控制器平台的Arduino板是相对便宜的。 Arduino的模块的最便宜的版本可以用手装配，甚至预组装的Arduino模块成本低于$ 50

跨平台 -  Arduino的软件（IDE）在Windows，苹果OSX和Linux操作系统上运行。大多数微控制器系统仅限于Windows操作系统。

简单，明了的编程环境 -  Arduino的软件（IDE）易于使用的初学者，但足够灵活的高级用户利用的为好。对于教师来说，它方便地根据加工的编程环境，让学生在这种环境中学习计划将熟悉Arduino的IDE是如何工作的。

开源和可扩展的软件 -  Arduino的软件发布为开源工具，可用于扩展通过有经验的程序员。语言可通过C ++库中扩大，人们希望了解的技术细节可以从Arduino的飞跃，以其所基于的AVR C编程语言。同样，你可以直接添加AVR-C代码到你的Arduino程序，如果你想。
