LiquidCrystal lcd(11, 12, 2, 3, 4, 5);
void setup() {

delay(1000);
}
void loop() {
// scroll 13 positions (string length) to the left to move it offscreen left:
for (int positionCounter = 0; positionCounter < 13; positionCounter++) {
lcd.scrollDisplayLeft(); // scroll one position left:
delay(150); // wait a bit
}
// scroll 29 positions (string length + display length) to the right to move it offscreen right:
for (int positionCounter = 0; positionCounter < 29; positionCounter++) {
lcd.scrollDisplayRight(); // scroll one position right
delay(150); // wait a bit
}
// scroll 16 positions (display length + string length) to the left to move it back to center:
for (int positionCounter = 0; positionCounter < 16; positionCounter++) {
lcd.scrollDisplayLeft(); // scroll one position left
delay(150); // wait a bit
}
delay(1000); // delay at the end of the full loop:
