15 Arduino示例代码 16 参考文档 概述 URM06是基于senscomp公司6500超声波静电换能器设计的一款大功率超声波。测量距离可达10米, 另外一个显著的特点是超声波探测夹角只有15°,而大多数的超声波是60°。这样就可以提高超声波测量角度分辨率。是机器人等应用领域壁障导航方案的首选. ...

Running the Code Now that our code has been created, we can load it onto the Arduino and get talking to an encoder. Open the serial monitor, make sure the data rate is set to 115200, and see the encoder work. One benefit of an RS-485 device is that you can talk to multiple encode...
