自从入手arduinon差不多半个月了，在window下几乎没有任何问题，下载，编程，编译，上传，运行。几乎没有任何问题。在linux编译成功，上传时下却总是提示找不到libncurses.so.5无法载入等错误信息，经过各种查找资料，终于搞定了。步骤如下：
（1）首先，由于我的系统永远是最新的，libncurses是6.0版本的，要找到libncures5版本的，终于在一台较老的chakra linux中找到了；分别拷贝到/usr/lib/和/usr/lib32/目录中，其中lib和lib64是一样的，lib32的32位的库目录
（2）接着，创建连接文件
cd /usr/lib/
ln -s libncurses.so.5 libtinfo.so.5
cd ../lib32/
ln -s libncurses.so.5 libtinfo.so.5
（3）最后就可以编译成功了。下面分享一个西游记中女儿情的程序：

硬件连接非常简单，只要将数字接口5连接到喇叭的正，喇叭的负接地即可。
