光电鼠标拍摄
OK,所以最后决定让我的手在Arduino平台上,看到所有的嗡嗡声是真的。我必须说,我留下深刻的印象。这是迄今为止我所见过的大多数开发人员友好的开发平台。它的主要优点:
这很简单。硬件是非常简单的,并使用标准的,通常可用的组件。的软件IDE是基本的,但功能:编辑器窗口,状态窗口,集成了串行终端。就是这样。
这是相当强大的。Arduino的diecimilla,我用基于ATmega168微控制器时钟频率为16MHz。
它是基于开放源码硬件和软件(如果你省略了商标争议商标的Arduino)。电路板设计是公开的。这导致了创造的几个变种和的克隆(Freeduino)的平台的普及做出了贡献。
电源,固件更新和串行通信通过一个单一的USB电缆。
它的可扩展性。Arduino板的主要之上,可堆叠的“盾牌”的概念是天才:)作为一个事实上,一个小的原型盾的第一件事是我做了这个平台。
所以,前一段时间,我遇到了这个伟大的光电鼠标黑客雪碧。我决定,这将是巨大的做我的第一个Arduino的项目(超越“Blinky LED”的例子,那是。)
第一步,剥离的无线鼠标便宜的台风无线鼠标/键盘组合。
