Morse project with function, parameters and switch

SOS code with 3 functions

const byte ledPin = 13;

void setup(){

// Use ledPin as output

pinMode(ledPin, OUTPUT);}

//Create a function for short blink

void shortBlink(){

// Make a single short blink

digitalWrite(ledPin, HIGH);

delay(200);

digitalWrite(ledPin, LOW);

delay(200);}

void longBlink(){

// Make a single long blink

digitalWrite(ledPin, HIGH);

delay(600);

digitalWrite(ledPin, LOW);

delay(200);

}

 

void morseBlink(char character) {

/*Morse blink is a function that only depends on one argument or parameters named character ( I choose that name ). This parameter is a variable of char type, char type is a number corresponding to ASCII characters */

// Translate character to Morse code

switch(character){

/*  switch is a common function in programing language and is an alternative to the "if, else" statements or instructions equivalent to if character =="s" */
