Arduino智能小车--只是随便一搞

标签：rem   智能   下载   返回   开心   its   ack   long   左旋转   

在某宝宝买的智能小车，挺精致的，开心的连接上打印机的线，结果端口都没有反应，

查了一下发现是少了驱动，博主用的mac os10.12.3

CH34x_Install_V1.4.pkg  

安装好之后我们再启动arduino 就可以看到新的端口了，选择他，我们就可以进行上传代码了。

只是对附赠源码进行了一下整理。。。

这个用到了红外遥控，需要一个IRremote库，打包资源在csdn下载里边自行下载，内附说明。感谢智宇科技--链接 感谢智宇科技--链接 感谢智宇科技--链接 感谢智宇科技--链接
