Today I was given an LCD display, I looked around and I'm quite positive I've found the correct datasheet.
Here's the datasheet I've found: http://www.jm.pl/karty/JM164ASPEC.pdf
On the back of the display, it said "PCB-JM164A-1" and searching for "JM164A" led me to the datasheet.

I have no idea on how to connect it to my Arduino and print text to it, it'd be really great if you could point me in the right direction. Also, is there a library which is compatible with this display?
(I have no experience with displays)



Start off by reading about the LiquidCrystal library on the main site. That ought to tell you everything you need to know! :)


It looks like a garden variety character mode LCD.  If you want a more complete datasheet for the controller then search for 'HD44780'.

You would use the LiquidCrystal library.  There's an extensive tutorial at the Adafruit website.
