SOS Alejandro

SOS Alejandro is an arduino code capable of switching on and off a LED with Morse code

Here's how you can make bold and italic text.

Here I'm going to explain the intructions of the Morse code:

Here's how the Morse code works:

  1. A dash in equal to three dots
  2. The space between parts of the same letter is equal to one dot
  3. The space between two letters is equal to three dots
  4. The space between two words is equal to dots

Here's how the Morse code woeks with arduino programming lenguage:

  1. Download the arduino software at this link.
  2. Check the drivers by clicking the device administrator (administrador de dispositivos).
  3. Select the unknown device (arduino)
  4. Click the right button over "unknown device" and update the arduino driver.
  5. Click on the option "Search drivers in the computer".
  6. Find the location of the arduino drivers, inside the arduino folder select drivers folder.
  7. Say yes to driver instalation.
  8. Access to Arduino Software and click in "Tools", then, select the "Arduino Board" and the "Port".
  9. We need to decide how long does it take to produce a dash and a dot. If the dot is two hundred miliseconds the dash will be three times more, that is six hundred miliseconds.
  10. digitalWrite(13, HIGH);// turn on the light delay (600); // Wait for 600 millisecond(s) = a dash. This code turns on the light during six hundred milisecinds
  11. digitalWrite(13, HIGH);// turn on the light delay (200); // Wait for 200 millisecond(s) = a dot. This code turns on the light during two hundred milisecinds
  12. //space between words is seven times a dot delay(1400);//Wait for 1400 millisecond(s)= seven dots. This code creates the empty space with no lights between two words
  13. Why is Firmata important? Becasuse is the filrmware the most important,because you to write custom firmware without having to create your own protocol and objects for the programming environment that you are using. In the future,it will be very important because we can change the internal control of any device
 
    void setup()
{
  pinMode(13, OUTPUT);
}

void loop()
{
  //S
  digitalWrite(13, HIGH);//turn on the light
  delay(200); // Wait for 200 millisecond(s)= a dot
  digitalWrite(13, LOW);//turn on the light
  delay(200); // Wait for 200 millisecond(s)off
  digitalWrite(13, HIGH);//turn on the light
  delay(200); // Wait for 200 millisecond(s)a dot
  digitalWrite(13, LOW);//turn on the light
   delay(200); // Wait for 200 millisecond(s)off
  digitalWrite(13, HIGH);//turn on the light
  delay(200); // Wait for 200 millisecond(s)a dot
  digitalWrite(13, LOW);//turn on the light
  delay(600); // Wait for 200 millisecond(s)off
  
  //O
  digitalWrite(13, HIGH);//turn on the light
  delay(600); // Wait for 600 millisecond(s)= a dash
  digitalWrite(13, LOW);//turn on the light
  delay(600); // Wait for 600 millisecond(s)off
  digitalWrite(13, HIGH);//turn on the light
  delay(600); // Wait for 600 millisecond(s)a dot
  digitalWrite(13, LOW);//turn on the light
   delay(600); // Wait for 600 millisecond(s)off
  digitalWrite(13, HIGH);//turn on the light
  delay(600); // Wait for 600 millisecond(s)a dot
  digitalWrite(13, LOW);//turn on the light
  delay(600); // Wait for 600 millisecond(s)off
  
  //S
  digitalWrite(13, HIGH);//turn on the light
  delay(200); // Wait for 200 millisecond(s)= a dot
  digitalWrite(13, LOW);//turn on the light
  delay(200); // Wait for 200 millisecond(s)off
  digitalWrite(13, HIGH);//turn on the light
  delay(200); // Wait for 200 millisecond(s)a dot
  digitalWrite(13, LOW);//turn on the light
   delay(200); // Wait for 200 millisecond(s)off
  digitalWrite(13, HIGH);//turn on the light
  delay(200); // Wait for 200 millisecond(s)a dot
  digitalWrite(13, LOW);//turn on the light
  delay(200); // Wait for 200 millisecond(s)off
  
  //space between words is seven times a dot
  delay(1400);//Wait for 1400 millisecond(s)= seven dots
