Hello All. First would like to apologize for the stupid questions but faced some brick wall here :D I have arduino uno r3, 20x4 LCD which I want to use for aquarium project. I have faced some probably known and easy issues. I'm running the LCD through I2C the address that is is 0x3F. I'm trying to print something on the display but with no luck all. The display is powered up and the 1st and the 3rd line are with field white boxes, the second and fourth are blank. Any help would be greatly  appreciated. Thank you in advance.

Have you looked through any of the previous threads covering this same topic? 

Try using the search box at the upper right to look for LCD I2C.  This will give you nearly 13,000 to pick from.
