学习Arduino有一个月左右了吧，今天尝试做了个小时钟，效果还不是很好，但是鉴于马上要出国读书了，还是想写一篇帖子，也算是交个作业以及表达一下对极客工坊这么好的学习之地表示感谢吧！
关于时钟性能的改进等日后有空了再进一步更新~~~话说自己大爱做时钟

元件清单：1.热敏电阻或LM35温度传感器（自己用的是热敏电阻，便宜点哇）
         2.DS1302时钟模块
         3.红外遥控器及红外一体接收头
         4.1602液晶屏



好了，废话不多说，上图，上视频~~

   基本上我的superclock的V0.1版本就是这个样子了，当然还存在很多问题，等日后有空了果断再更新一下，只因我个人大爱时钟，希望能做出更加个性化而且功能完善的时钟吧，先mark下日后需要改进的地方：
1.遥控设定时间
2.闹钟设定

PS：视频中也提到了Remote的库和Arduino本身的tone函数存在冲突，暂时功力还不够深厚，等日后好好研究一下再改进！
鄙人不才，还望各位大神指点！另真心感谢极客工坊提供这么好的学习平台！

原来有人做了啊，我还做了一个呢不过我用的是1307+DHT11，有时间设置和温度和湿度

龙腾东山 发表于 2013-2-1 20:16:42

有空模仿一个,谢谢了!

ogre_c 发表于 2013-2-2 15:04:04

谢谢楼主，学习了，因现有的苹果遥控器闲置，所以模仿了楼主的代码，用它遥控小表，兼职遥控个电视啥的。
主要硬件：arduino uno，一样的液晶屏和时间模块，红外收发头，蜂鸣器，sht10温湿度传感器。
