LiquidCrystal::cursor
void LiquidCrystal::cursor();
This function enables display of the cursor. The cursor is displayed by default, so you only would need to call this after a call to noCursor();
Usage:
LiquidCrystal lcd(8, 9, 4, 5, 6, 7);
lcd.begin(16, 2);
//do something and want the cursor gone
lcd.noCursor();
//do something else and want it back on
lcd.cursor();
