<哈里·波特>的故事里面,魔法界的新闻报纸都是动画的,配图带有动画效果.能够回放新闻的主要场景. 初次看到这个,感觉还挺新鲜的.不过现在,Blink 这样的 App 可以让这个魔法世界的幻想距离现实更进一步. Blink 是 Microsoft 的一款 Windows Phone App 应用,它能够将一段视频进行处理,生成一个短动画图片,然后,你就可以在社交网站上共享这动画了. 当很多人都分享这些动画时,Blink 网站 的页面看上去就和哈里·波特魔法世界的报纸很像很像了. 接下来,只要 电…

不使用 delay() 函数而使 LED 闪烁 有些时候你需要同时做两件事.例如,你可能希望在读取按键按下状态同时让LED闪烁. 在这种情况下,你不能使用 delay(),因为Arduino程序会在delay()中停顿. 如果按键被按下的同时,Arduino正在暂停等待 delay()结束 ,你的程序也将会错过按键的按下. 这个演示展示了如何闪烁LED而不使用 delay().它点亮了LED,然后记录下时间.然后,每一次通过 loop()循环, 检查闪烁设置时间是否到达. 如果是,它的点亮或熄灭…

向量空间(Vector Spaces) 向量空间又称线性空间,是线性代数的中心内容和基本概念之一.在解析几何里引入向量的概念后,是许多问题的处理变得更为简洁和清晰,在此基础上的进一步抽象化,形成了与域相联系的向量空间概念.譬如,实系多项式的集合在定义适当的运算后构成向量空间,在代数上处理是方便的.单变元实函数的集合在定义适当的运算后,也构成向量空间,研究此类函数向量空间的数学分支称为泛函数 Example: R2(均为二维实向量) eg:…
