用了两个星期的下班时间完成了基本动作,可就是升级到蓝牙控制就是没有反应,手机能收到开机反馈,可手机发送命令就是没有反应,试过串口监视测试也没有问题,请大神帮助解决!
/*项目名称:遥控蜘蛛机器人
*作者:小川子,许康元
*日期:2018/09/30
*参考:Sunfounder设计的爬行机器人
*概述:通过组装蜘蛛机器人,感受Arduino的控制魅力,与单片机的强大。通过实践感受到自己能力的欠缺之处。
*---该项目前期是用Arduino UNO进行制作的,但是由于UNO 太大了,于是在项目完成之后改用 Nano
* 进行重新组装
*---在安装机器人没有问题后再进行本程序的调试
*---该程序动作函数参考Sunfounder设计的爬行机器人的演示代码
*---请确保正确安装了库文件
