Can I get more details on the wiring?
I am using the description by kent I believe.
Connecting BINH is preventing it from working. It clicks but the echos
immediately (0 inches).
without BINH, I get it to run but with minimal distance of 18".
Maybe someone can point me to a more detailed wiring set up?
thx.

Hi Jeff,
The Polaroid sensors work pretty darn well. I've been able to get
1" resolution from 8" to 130"++ (reportedly they work to 35 ft - my room's
not big enough to try this out). I was able to get mine working in about 10
minutes. Basically, just FTP the code, attach a few wires and it works. It's
WIRE-N-PLAY! The only "modification" required is that one of the motor driver
chips must be pulled out to access some output signals. It's really pretty
cool.
