I had the Ping working to 10ft, which I believe is the max distance. It was reading the distance, then speaking the measurement using the Quadravox sound module Parallax sold in the past. It would say how many feet and inches something was from the sensor. The sound was for testing so I could walk in front of it and not have to watch the debug window.

By the way, make sure the sensor isn't sitting on something like a table top. It has to be up off the surface a bit, otherwise, it seems to detect that. I'm building Halloween props, so I have the Ping sensor paired up with the PIR sensor, which detects movement out to 20 ft. Not sure what you are building, but you can use the two together pretty effectively. I'm using them for safety switches in case people get to close to a prop. I use the PIR sensor to detect movement, then turn on the PING sensor to make sure people aren't within 5ft of the prop. Yes, it is fenced off, but someone will always find a way to lean over or sneak too close.
