after looking at the display choices i decided i wanted to use a display that ran on the ic buss. this takes up only two pins and is very fast. as there was no current library i decided to write one, and in turn am making it available to the arduino community. api compliance: i have also put together a  written for the following hardware clcdblb, a textual lcd but also works with smaller or bigger lcd by giving the size of the current lcd in the constructor. works through ic by using pin a(sda) and pin a(scl) on an arduino uno r. some pullup resistor(i use k ohms) might be needed  there are few lcd ic libraries around. for whatever reason, they all have same name liquidcrystal_ic so it is hard to judge which one to use. they all follow hitachi protocol for multiline character display. looking at github i see one build in with some minor issues. please advise which to use,

like many on this discussion group, i bought an ic lcd device for my arduino only to find that the documentation is either nonexistent or, if it does exist, just wrong. having spent the last few nights trying out all the options i could find, i thought i'd pull together the steps i used to get my lcd going. this library allows an arduino board to control liquidcrystal displays (lcds) based on the hitachi hd (or a compatible) chipset, which is found on most textbased lcds. the library works with in either or bit mode (i.e. using or data lines in addition to the rs, enable, and, optionally, the rw control lines). the blue potentiometer on the ic lcd (see the figure below) is used to adjust the backlight for better display. copy the folders under the library folder to the libraries folder in arduino (if you cannot find the path in arduino, open arduino ide, click file >preferences, and you can see the path in the  these small circuit boards on the back interface a wire ic "i squared c" bus (plus ground and v power) to the many pins on the lcd display itself. this allows running the display from only signal pins on arduino. the yourduino robored (uno compatible) has a pin connector that works well for this type display.
