第一次玩这个，买了一个炸弹套件，无法使用求助

我已经按照教程安装完毕，但是无法输入源代码，显示代码如下：
教程里有要让我下载一个什么库文件，但是网页已经失效无法下载。
在线求助中：：

使用 1.0  版本的库 Wire 在文件夹： C:\Users\Administrator\Desktop\arduino-1.8.4\hardware\arduino\avr\libraries\Wire
exit status 1
为开发板 Arduino/Genuino Uno 编译时出错。

现在通电后液晶屏只有很多方黑色方块，什么都没有

从报错信息看应该是库的问题，如果原链接的LiquidCrystal_I2C无法找到，可以试下这个链接下面的库文件。

如果烧录成功后无法正常显示，可以手动调节下屏幕后面的电位器，可以调下对比度。

估计买到了劣货。
