Arduino是一个任何人都可以快速上手使用的电子控制平台，可能在硬件工程师的眼中它仅仅是一个简单的8位机最小系统，但对于更多的没有硬件背景的人来说（特别是软件工程师），Arduino为他们打开了一扇通向硬件领域的窗口，这扇窗连接的是一个叫做开源硬件的世界。??Arduino注重实际动手操作应用，只要掌握了一些基本的电子学知识，就能制作出很有意思的硬件交互作品。正是基于这个原因，本书以基础的电子学知识为纽带将各个章节联系起来，通过简单的应用介绍了Arduino中数字量和模拟量的处理方式。用Arduino完成的形形色色的电子作品都是基于这些基础知识实现的，本书的作用只是引领你走入Arduino的精彩世界，希望大家在读完本书后充分发挥各自的想象力，去制作更有意思的电子作品。

it is through his engaging in public diplomacy that mr. zhao qizheng es to recognize its significance for china. this has prompted him to summarize his practices in and reflections on public diplomacy over the past 20 years. it is also a record of chinas integration into the world and the worlds growing understanding of china. in thiook, the vision of international munication iroadened as an important element of public diplomacy, and the bar in international munication is raised to better introduce china to the outside world. more than just a collection of documents, or a minute detailed account, it is enlightening for both academic thinking and real life operation.
