今天我们来讨论一下我们如何利用单片机做出一些炫彩的效果,而昨天好像是七夕节,很多人都把它当做了情人节,那么我们来做一个浪漫的“I Love u”;今天我就把代码写出来,而不再是截图挂出来。效果图我也就拍出来了,你们如果有单片机可以自己复制代码下来看一些效果。(其实这一次的代码有一点跨度大了,毕竟前面我并没有说的很深入,现在一下子又变得看不懂了,不过慢慢来,我会在以后的博客中把后边的讨论写详细一点)代码如下,注释我来写了一部分,但是不全,我会慢慢把它补齐。
效果大致如我以下描述:首先,LED灯慢慢的像流水灯一样一个接一个亮起来;而后是点阵从靠近LED灯的那一排开始亮起来,就像蛇一样游动,第一排是从第一个亮完最后一个,从第二排接着第一排的最后一个那侧开始亮(就像蛇游动)一直到最后一排;接下来是数码管,数码管只有那一个点“.“亮,像流水灯一样亮起来;前面效果都完之后所有的LED灯,点阵,数码管都会全部亮起来;点阵就会显示“I love u”那句话了,不过不是同时显示,成一个先后顺序。
(如果代码和注释中有误,请指出,我会第一时间和你沟通并改正,谢谢)
