Blue Robotics Ping Arduino Hardware Serial Example

ping1d-simple-hardware-serial.ino

/**
    This example is targeted toward the arduino platform

    This example demonstrates the most simple usage of the Blue Robotics
    Ping1D c++ API in order to obtain distance and confidence reports from
    the device.

    This API exposes the full functionality of the Ping1D Echosounder

    Communication is performed with a Blue Robotics Ping1D Echosounder
