Arduino Project: Morse Code

Date: By Unknown
Today during my conceptual physics class, my teacher introduced the Arduino developing kit, and we started working on it. I had a little experience of coding so it was not hard for me. Therefore, I created this Arduino project that can control the LED on the broad to spell my name using Morse code.

This is the code that I wrote
>>>
int LED = 13;
int dot = 300;
int dash = dot * 3;
int elemPause = dot;
int charPause = dot * 3;
int wordPause = dot * 7;
char fName[] = "allen";
char lName[] = "lin";

void setup() {
  pinMode(LED, OUTPUT);
}
void MorseDot() {
  digitalWrite(LED, HIGH);  
  delay(dot);
}
void MorseDash() {
  digitalWrite(LED, HIGH);  
  delay(dash);
}
void MorseElemPause() {
  digitalWrite(LED, LOW); 
  delay(elemPause);
}
void MorseCharPause() {
  digitalWrite(LED, LOW);
  delay(charPause);
}
void MorseWordPause() {
  digitalWrite(LED, LOW);  
  delay(wordPause);
}
void longPause () {
  digitalWrite(LED, LOW);
}
void pickLetter(char x){
  switch (x) {
      case 'a':
        MorseDot();
        MorseElemPause();
        MorseDash();
        MorseElemPause();
        break;
      case 'e':
        MorseDot();
        MorseElemPause();
        break;
      case 'i':
        MorseDot();
        MorseElemPause();
        MorseDot();
        MorseElemPause();
        break;
      case 'l':
        MorseDot();
        MorseElemPause();
        MorseDash();
        MorseElemPause();
        MorseDot();
        MorseElemPause();
        MorseDot();
        MorseElemPause();
        break;
      case 'n':
        MorseDash();
        MorseElemPause();
        MorseDot();
        MorseElemPause();
        break;
    }
  MorseCharPause();
}
void loop () {
  pickLetter(fName[0]);
  pickLetter(fName[1]);
  pickLetter(fName[2]);
  pickLetter(fName[3]);
  pickLetter(fName[4]);
  MorseWordPause();
  pickLetter(lName[0]);
  pickLetter(lName[1]);
  pickLetter(lName[2]);
  MorseWordPause();
  longPause();
}
>>>

It was a cool experience and I planned to make some videos teaching people how to code Arduino on my Youtube channel about science. Please subscribe my channel if you found the content really interesting(link).

7 Musical Modes - I.D.P.L.M.A.L.

By Date:
There is a way to create 7 kinds of scales easily just by using one chord. This method is called the I.D.P.L.M.A.L. I.D.P.L.M.A.L. refers to: I onian(I)  D orian(ii)   P hrygian(iii)   L ydian(IV)   M ixolydian(V)   A eolian(vi)   L ocrian(vii) The way to memorize it is: I   D on't  P lay  L ike  M iles  A fter  L unch (Miles Davis was an influential musician in the history of the 20th century music) The way to use this method is to start the scale from a different note.  For example, if I have a scale which contains only B flat,  then the one below will be an  F Major scale , which  starts from F(I) : F - G - A - B flat - C - D - E - F  this one will be an F Dorian scale , which starts from G(ii): G - A - B flat - C - D - E - F - G  and this one will be an F Mixolydian scale , which starts from C(V): C - D - E - F - G - A - B flat - C By using the 7 musical modes, you wi...

A Social Marketing Principle - The V.R.I.N. Principle

By Date:
Today, I saw an ad on Youtube that provides a social marketing course, and it teaches people the key to achieve in the social market. I am just being curious and I went up and signed up for a free training webinar. Unfortunately, I am not affordable for the price of the course. It is $699. But the good news is that I learned a principle of social marketing. It's called the V.R.I.N. principle. I searched it on the web and I found it pretty interesting, it is a way of methods on debugging a company's business strategy and create a sustainable competitive resource for the business. V aluable: If it is useful, ideal, or creative. R are: If it is unique, special, or literally, rare. I mperfectly imitable: If it is easy to be copied by others. N on-substitutable: If it is able to stay on the market as time passes. This method is useful when you just have an idea of starting a business or online platforms. You can now easily check a company with the method and fix the mistakes. ...

Ancient Architectural Style & Sketchup Practice

By Date:
Today in history class, I learned some different types of architectural style in different ancient time periods -- Ancient Rome, Ancient Greece, and Ancient Egypt. We were assigned to create an ancient style architecture using the Sketchup  program. So, I started up by doing some research with the style of those types of ancient buildings, and this is what I got: Ancient Rome Style: made of stone, arches, pillars, and domes. Ancient Greece Style:   made of columns, door and window openings. Ancient Egypt Style: made of sun-baked mud brick or stone, post and lintel structure. Then I searched "sketchup tutorial", and found that the company has already made a list of video tutorials . They are really helpful, and it helps me a lot to get familiar with the drawing tools. After watching some video tutorials, I first started with a 2D-design draft on a piece of paper using the Ancient Rome style. It looks like this: Then I worked on the design using...
