Hello guys, I am interfacing 20*4 LCD display with arduino mega 2560. I am trying a basic example of "Hello World". But it is not showing anything on display. I am attaching my code and diagram of display.
Please help me out.

...But it is not showing anything on display....
I see something, blocks on the first and third rows. This is quite significant.
You might want to look at some of the previous forum posts on this topic, there are dozens, possibly hundreds.
The size of the display and the type of Arduino do not matter. Look for the key words LCD and blocks.
