What part of this do you not understand???

If you don't see the boxes than no amount of tinkering with the other wiring, the IDE, the libraries, or the program code (sketch) will help.

Hi everyone.
I have exactly the same problem with exactly the same LCD, but I can see the black boxes.
So everything's fine but I cant print anything on my LCD :(

thx for answering!
I had trouble, but everything works fine now. I had no 10k potmeter, but using two 10k resistors just works fine.
Thanks again.

I wrote a little script for linux which may be fun to try: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1253025207

btw, does anyone know if it is possible to use the OBDuino system, I reported the sys a few months ago but no luck so far.
