This example sketch shows how to use the setCursor() method to reposition the cursor. To move the cursor, just call setCursor() with a row and column position. For example, for a 2x16 display:
lcd.setCursor(0, 0); // top left
lcd.setCursor(15, 0); // top right
lcd.setCursor(0, 1); // bottom left
lcd.setCursor(15, 1); // bottom right
I am not able to understand the above code.Can anyone please give the clarification for the same?
The line lcd.setCursor() moves the cursor. The cursor is the position of the lertter you want the text to begin displaying at. lcd.setCursor() takes two values: an x position and a y position. It takes them in this order: lcd.setCursor(x, y).
A 2x16 display means that it has 2 rows and 16 columns of characters, or 2 y values and 16 x values.
In Arduino code and in most c-type languages you start counting at 0, this means that to get the first column you need to tell the Arduino to look at x of 0. Or to put a letter in the last column on the first row you would need to tell the Arduino to move the cursor to: (15, 0).
The display will look like this:
