　　简单的从机工作但甜美的用户界面解决方案

　　像Arduino一家小型计算机板不仅仅是一个重视教育的车辆。生态系统得到专业工程师的热情响应，解决了无数的感官和控制挑战。它们可以从简单的连接传感器到控制机械或简单机械的马达或执行器。结合一个Arduino开发板和I/O或电机驱动盾牌可以满足工程需要的运动控制。一个生态系统像Arduino开源性质意味着有很多的项目公布在网上，可以提供一个定制的应用程序的一个发射台。有预先写好的代码在制造商网站或独立的GitHub来源众多。图1是用于控制从GitHub的Arduino机器人代码摘录。

　　User interface choices

　　At the other end of the connection， a user interface is needed. Equipment such as a robotic arm or a motorized probe may need little more than a set of controls for basic movements like forward/back， left/right， or clockwise/counter-clockwise rotation.

　　Smartphone app？

　　One solution is to use a smartphone as the main user interface controller. This has been widely adopted where consumers need to interact with smart “things” such as domestic heating or lighting systems， security devices or drones. The smartphone has many strengths， including its high resolution color display for presenting attractive instruments， sophisticated multi-touch capability， and versatile connectivity encompassing cellular， Wi-Fi® and Bluetooth®。 They are ubiquitous， and can be easily turned into a suitable controller simply by loading an app designed to accompany the new product.

　　For some projects， however， developing a custom app may be costly， time consuming， and outside the core skillset of the development team.
