SOS Marina

SOS Marina 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 is 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 five dots

Here's how the Morse code works with arduino programming language:

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 and click "next".

7. Say yes to driver installation

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 miliseconds
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 miliseconds.
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. Firmata is the most important fileware. With firmata we can control Arduino from Software installed in the computer without write any letter in Arduino code. You can comunicate, this allows you to write custome firmwear. In the future, fillware will be very important because be will be able to change the intern controll of any dispositive.
