Story

Introduction

Our Arduino User Group, we_create, has finally launched our first project! We decided that we needed some help in building a project, so what better way to ask for help than an SOS signal?

We are not pros, so please do not make savage comments about our junkie coding skills. We are all newbies, so your advice, not your hate, is appreciated.

How We Did It

I don't know.

Just kidding. I (pianoplayer7) decided to get the group together and to build some simple projects to teach them the basics about Arduino. As I showed them the LED Blink project, shaubrich14 shouted out the idea of Morse code. Another person (rramont3) started to fool around with the code, and we - somehow - came up with this project. (I told you I don't know how we did it.)

Code

Morse Code SOS

void setup() {
  pinMode(13, OUTPUT);
}

void loop() {
  int ledPin = 13;
  digitalWrite(ledPin, HIGH);
  delay(100);
  digitalWrite(ledPin, LOW);
  delay(200);
  digitalWrite(ledPin, HIGH);
  delay(100);
  digitalWrite(ledPin, LOW);
  delay(200);
  digitalWrite(ledPin, HIGH);
  delay(100);
  digitalWrite(ledPin, LOW);
  delay(300);
  digitalWrite(ledPin, HIGH);
  delay(500);
  digitalWrite(ledPin, LOW);
  delay(200);
  digitalWrite(ledPin, HIGH);
  delay(500);
  digitalWrite(ledPin, LOW);
  delay(200);
  digitalWrite(ledPin, HIGH);
  delay(500);
   digitalWrite(ledPin, LOW);
  delay(300);
  digitalWrite(ledPin, HIGH);
  delay(100);
  digitalWrite(ledPin, LOW);
  delay(200);
  digitalWrite(ledPin, HIGH);
  delay(100);
  digitalWrite(ledPin, LOW);
  delay(200);
  digitalWrite(ledPin, HIGH);
  delay(100);
  digitalWrite(ledPin, LOW);
  delay(2000);
