  SparkFun labored with love to create this code. Feel like supporting open source hardware? 
  Buy a board from SparkFun! https://www.sparkfun.com/products/14667

  This example prints the distance to an object.

  Are you getting weird readings? Be sure the vacuum tape has been removed from the sensor.
