Maybe you can try this

Start with a sketch that does simple Morse code:
int pin = 13;

void setup()
{
pinMode(pin, OUTPUT);
}

void loop()
{
dot(); dot(); dot();
dash(); dash(); dash();
dot(); dot(); dot();
delay(3000);
}

void dot()
{
digitalWrite(pin, HIGH);
delay(250);
digitalWrite(pin, LOW);
delay(250);
}

void dash()
{
digitalWrite(pin, HIGH);
delay(1000);
digitalWrite(pin, LOW);
delay(250);
}

I find it when I googling,

I also badly need a guide on how to build a library for arduino in that lcd. Hope someone answer. I appreciate the help. Thanks in advance!
