Dj, what serial lcd screen did you use for you omnibot 2000?
Is there a brand of lcd you especially like/use?
Also, all i can find is i2c serial lcd screens when i search serial lcd screens on ebay.
?
Do you have a tutorial on lcd screens at all? thinking of putting one in the front of my wall-e when im done phase 1.
Do you have a pic of the setup for your lcd?
Thanks.
For things like screens, that's hardware. Look under the hardware tab.

There is also this one. is this one right?

1. Small 2x8 style LCD displays, usually I2C or Serial (like the first of your links)
2. LCD displays such as monitors, tvs etc. (like the second link)
They both work differently. Typically the second type need a video input through VGA or composite (or possibly HDMI these days?). The EZB cannot output anything to this type of screen.
There are the smaller LCD displays which are Serial or I2C, I've yet to source a serial one to fit my current project but I2C are all over eBay. Be wary of which one you get and search on here first as the one I bought was useless as it had no decent documentation.
You can use either Serial (3 wire, connects to Digital Port) or I2C (4 wire, connects to I2C Bus). I2C is more complicated than Serial, at least to me it is...

That should be a simple serial LCD.

Have a read of this topic here to see just how difficult I2C can be.
On the LCD hardware tutorial page there Is a link to search eBay
So does the title I2c serial lcd mean its serial and i2c compatible?
May I ask what you need the LCD to display?
If it has 4 wires it's probably I2C and not worth the time or effort.
Any ideas?
While I'm not 100% sure it's the right thing I am 99% sure.
It's 5 pin, but only 3 are needed;
Wire a servo extension as follows;
Black to pin 5
Red to pin 3
White to pin 1 or 4 (unsure which, it could be either)
Wait for someone to confirm before buying, I wouldn't want someone to get the wrong thing from something I've said.
