Parallax Ping + Arduino
Hello,
I'm having trouble getting proper readings from a Parallax Ping. I've followed the tutorial on the Arduino site with no luck.
The problem I'm having is the readings in the serial monitor are mostly 0in or 4in. It never changes with different distance targets. The "active"LED flashes like units I've seen on YouTube.
It's a very simple set up, so I'm sure everything is hooked up and programmed correctly. Could this unit be defective?
Thanks

This may be a ground issue. After some more troubleshooting I found that if I wiggle the ground or touch different metal parts it reads very accurately. I still can't get stable readings though.
Anyone have experience with these?
