New to Arduino. Thought I'd start with a classic intro program "hello world" using the led and morse code.
Nice straightforward language!
// Hello World in Morse Code
//Map led to port 13
const int LED = 13; //LED connected to port 13
//Define needed durations, using Morse code standard multiples, which use the duration of DOT as a base
const int DOT = 100; //Morse Code Dot duration
const int DASH = DOT3; //Morse Code Dash duration
const int SPACE = DOT; //Morse Code intra-letter pause duration
const int LETTER = DOT2; //Morse Code inter-letter duration
//assumes one space preceding it (normally Dot3)
const int WORD = DOT7; //Morse Code inter-word duration
const int PHRASE = DOT*50; //Arbitrary inter-phrase duration
void setup() {
// initialize the digital pin as an output.
pinMode(LED, OUTPUT);
}
//Define Dot and Dash
void dash() {
digitalWrite(13, HIGH); // set the LED on
delay(DASH); // DASH duration
digitalWrite(13, LOW); // set the LED off
delay(SPACE); // Space duration
}
void dot() {
digitalWrite(13, HIGH); // set the LED on
delay(DOT); // DASH duration
digitalWrite(13, LOW); // set the LED off
delay(SPACE); // Space duration
}
//Define needed letters
void letterD() {
dash();
dot();
dot();
delay(LETTER); // Letter duration
}
void letterE() {
dot();
delay(LETTER); // Letter duration
}
void letterH() {
dot();
dot();
dot();
dot();
delay(LETTER); // Letter duration
}
void letterL() {
dot();
dash();
dot();
dot();
delay(LETTER); // Letter duration
}
void letterO() {
dash();
dash();
dash();
delay(LETTER); // Letter duration
}
void letterR() {
dot();
dash();
dot();
delay(LETTER); // Letter duration
}
void letterW() {
dash();
dot();
dot();
dash();
delay(LETTER); // Letter duration
}
//Loop
void loop() {
letterH();
letterE();
letterL();
letterL();
letterO();
delay(WORD);
letterW();
letterO();
letterR();
letterL();
letterD();
delay(PHRASE);
}
(maybe there already is one?)
