I have purchased the Ping))) sensor. while using it with the Arduino UNO and the sample included on the website, I only get a reading of 144 inches.

Does this mean it is defective?

    I would double / triple check the wiring and the program - maybe the sample program isn't 100% right out of the gate?

    That reading seems higher than the PING))) should be able to return at maximum distance. Is the green LED on the PING))) blinking during program execution? Be sure the microcontroller I/O pin is returning to an input following the trigger pulse.
