Arduino nano programming basics.

Program will not fit into space provided.
I will send the first and last which is where the problem exists.

void setup() {
// put your setup code here, to run once:
// put your main code here, to run repeatedly:
// the loop function runs over and over again forever

// A DA is equal to 3 dits
// The space between parts ot the same letter is equal to one dit
// The bspace between two letters is equal to three dits
// The space between two words is equal to sevin dits.




// the setup function runs once when you press reset or power the board
void setup() {
// initialize digital pin LED_BUILTIN as an output.
pinMode(LED_BUILTIN, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {

digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)
delay(300); // wait for a second. DA Z
digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(100); // wait for 5 second.
digitalWrite(LED_BUILTIN, HIGH); // turn the LED on (HIGH is the voltage level)

and the last..

digitalWrite(LED_BUILTIN, LOW); // turn the LED off by making the voltage LOW
delay(5000); // wait for 5 second

}
