Hey guys,
Im looking for an LCD display for an arduino school project and im overwhelmed with all of my options. All I need it to do is display text. No buttons required... I would also prefer that it has a daughter board so it doesn't use so many arduino output pins. What I really want though is something reliable with well documented code.... This one looks decent but the reviews say the code is not well documented etc.
Any good reccomendations for a cheap LCD display with well documented code?
It's nonsense. The item you link to is fine and of a popular type. "not well documented" means no more than that the code for a 16x2 display in the IDE doesn't work with it. This is because that code is for a bare display while this display is on a shield. I believe all the 16x2 shields are wired the same way and it is simply a matter of changing one line of code. You might find
LiquidCrystal lcd(8,9,4,5,6,7);
fixes that.
Using an I2C shield as mentioned is a good idea as they use two signal pins but, while the above uses six, the buttons only use one, and you still have access to the others. For all that, you get the display on a handy shield
I2C means it only uses two pins, and those pins are actually a bus, so many I2C devices can share.
Piece of cake to program: the sample code worked right off the bat.

Hi,
Well documented code used by thousands is HERE:
And the style is what I like cause I wrote it
That said, suggestions and improvements always welcome!
