自制带有开机音乐的可显数字温度计

说来也不顺，知道她过生日的时候，已经距她过生日还有仅仅4天的时间，时间很紧，也不知道送些啥，一想，自己这些天一直在做关于单片机的东西，索性利用身边的材料，做一个东西给她，也挺有意义的。但因为平时忙着复习考研，所以注定做得东西不能太复杂了，否则根本完成不了，后来也就决定做这个温度计了。电路也不难，程序自己也见过，大概改改也就差不多了。后来感觉仅仅显示温度也太单调了，就加了音乐功能，一首《隐形的翅膀》也不错。

从周三开始，每天晚上11：00开始做，到今天，总算研制成功吧！有点遗憾的是，身边没有2-4译码器，所以LED驱动的不好，就算加了两个上拉排阻，显示的还是挺暗！
