How Can I Match My LCD Labels to a Tutorial's Labels for an Arduino Project?

[opus]

Hi.
I'm trying to get something started on an Arduino Project and I've never done one before, so I'm looking for a little clarification.
If you have a look at the posted images, you can see that the "labels" for the LCD screen for the tutorial and aren't the same as the labels for the LCD screen that I have. I'm wondering how I can decipher between them so mine will match the authors?
Here's a link to the project.

Oops. Can't do it without extra circuits and/or some messy programming.

The problem is the original project sends data to the LCD one bit at a time over one wire labeled SDA (and a Clock signal on SCL), the LCD you have wants 8 bits of data at a time to the connections labeled D0 thru D7, along with some other control or addressing information on 6 more connections.

Save yourself a headache (or three) and try to get an LCD display that matches the project.

Sorry.

Tom

p.s. Let us know how it turns out!

Unreadable, it will be difficult to help. Picture on the left is rather strange, I didn't know Fritzing allows connections to rather random points on the object.

VCC and GND are trivial. The other two looks suspicious, unless I am misunderstanding something. Hitachi LCD requires much more connections to work (don't remember how many, if memory serves me well it depends on the mode of operation, but it is something like 8 minimum).

I think it has a mode of operation that allows using just four lines, but I can be wrong.

Well shoot. Looks like Ill look for another project that matches what I have. Thanks everyone.

If you like the project it should be easily possible to modify just the way LCD is connected (although what I see would make me very careful about the rest of the project).

I think Ill just find one that will work as I just want one that will get the parts and stuff working. Found a couple that seem to match

Awesome thank you
