Hey guys,
I would like to know if I need to change or insert any new command to the example "HelloWorld" in arduino to display in two lines if i am using 16x2 lcd display. Also what is the command or how can I move the message on display so that its in the center.
Thanks. Im just learning so im pretty new to this.
That's not very helpful advice, when there are two 0s in the statement. Which one should be changed?
OP:
Change one 0 to something else, like 1. Observe the results. Then, change it back to 0, and change the other 0 to 1. Observe the results. Now, you know which argument affects the row and which affects the column.
Use that knowledge to put text where you want on the LCD.
If you want to centre the text, first call strlen on the string you want to display.
This will give the number of characters in the string, and allow you do some simple arithmetic to enable you to put the cursor in the right place before printing the string.
