Make a S.O.S signal using LED and Arduino

int redLED = 13; // Setting Value of redLED as 13
int dit = 150; // Setting Value of dit as 150
int dah = 500; // settiing Value of dah as 500
int longWait = 1000; // setting value of longW as 1000

void setup() {
pinMode (redLED,OUTPUT); // defining RedLED as OUTPUT
}
void loop() {
  
// DIT

digitalWrite (redLED,HIGH);
delay(dit);
digitalWrite (redLED,LOW);
delay(dit);

//DIT

digitalWrite (redLED,HIGH);
delay(dit);
digitalWrite (redLED,LOW);
delay(dit);

//DIT

digitalWrite (redLED,HIGH);
delay(dit);
digitalWrite (redLED,LOW);
delay(dah);

//DAH


digitalWrite (redLED,HIGH);
delay(dah);
digitalWrite (redLED,LOW);
delay(dah);

//DAH

digitalWrite (redLED,HIGH);
delay(dah);
digitalWrite (redLED,LOW);
delay(dah);

//DAH

digitalWrite (redLED,HIGH);
delay(dah);
