Lcd.clear

Using Arduino Project Guidance

Hi all,

at the moment im working with a lcd screen connected to my Arduino.
I have a lcd screen with 2 rows. I was wondering if there is a way to clear only the second row like:

lcd.clear(0.1)

but this is not a option is there a other way for this?

You can overwrite the line with spaces

Create your own function that writes a line of spaces to your chosen row of the LCD

void clearRow(byte rowToClear)
{
  lcd.setCursor(0, rowToClear);
  lcd.print("                ");  
}

Call it with the row number to clear eg

clearRow(0);  //clear the first row of the LCD

clearRow(1);  //clear the second row of the LCD

You could also position the cursor in the function ready for the next print if that was helpful and even pass the column as a parameter
