簡單的從機(jī)工作但甜美的用戶界面解決方案

　　像Arduino一家小型計(jì)算機(jī)板不僅僅是一個重視教育的車輛。生態(tài)系統(tǒng)得到專業(yè)工程師的熱情響應(yīng)，解決了無數(shù)的感官和控制挑戰(zhàn)。它們可以從簡單的連接傳感器到控制機(jī)械或簡單機(jī)械的馬達(dá)或執(zhí)行器。結(jié)合一個Arduino開發(fā)板和I/O或電機(jī)驅(qū)動盾牌可以滿足工程需要的運(yùn)動控制。一個生態(tài)系統(tǒng)像Arduino開源性質(zhì)意味著有很多的項(xiàng)目公布在網(wǎng)上，可以提供一個定制的應(yīng)用程序的一個發(fā)射臺。有預(yù)先寫好的代碼在制造商網(wǎng)站或獨(dú)立的GitHub來源眾多。圖1是用于控制從GitHub的Arduino機(jī)器人代碼摘錄。

　　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.
