教你用Arduino制作Buzz Wire游戏

在这个有趣的项目中，我们将学习如何使用Arduino制作嗡嗡声加MP3音的游戏，可以用于教学或亲子娱乐。网上都是用蜂鸣器来发音，这里为了增加趣味，增加了随机MP3音播放。
这里主要是受了Mr.Beans的电影的启发。当时看完留下了深刻的印象，后来转念一想，可以DIY一个，应该不难。

以下是完成此项目所需的核心部件：

1 x Arduino UNO或类似产品。

1 x铁丝两米。

1 x I2C LCD1602。

1 xDF的MP3模块。

1 x压电蜂鸣器。

3 x快速连线器。

IIC LCD主要显示钩子碰到铁丝的出错次数和胜利信息。GND连钩子，D9连铁丝，D10连一个铁环（终点-钩子触动这里会有从buzzer发出的胜利音乐）

烧录成功

这是用到的文字转mp3软件，mp3文件要拷贝到mp3模块里。细节参考DF wifi相关产品。
