ARDUINO
PROJECT – MORSE CODE WRITER

LESSONS

You should have looked at all lessons up to and including Lesson 11 before starting this project.

DESCRIPTION

In this project, you will create a program that can easily display any message in Morse code by using an LED to blink the code. The setup is very similar to the Practice example in the void functions lesson. However, in order to be even more efficient at writing any message, you will create a void function for every single letter in the alphabet. So 26 void functions. You probably simply want to call them a(), b(), c(), d(), …

HINT

The following tree shows you how to figure out a letter based on a sequence of dots and dashes. You can also use it to save you a lot of time when creating your functions. For example, the letter P is simply the W with a gap and a dot. So you could actually call w() and then gap() and then dot() to create the letter P’s function. (I wish I would have thought of this before I wrote my code!)

Note: The function F() is reserved for something else. You can use lower case f though, so f(). Or you can use F2().

TIMING RULES

• The length of a dot is 1 time unit.
• The length of a dash is 3 time units.
• The length of a normal gap is 1 time unit.
• The length of a gap between letters is 3 time units.
• The length of a gap between words is 7 time units.

PROJECT EXPECTATIONS

Create the program. Make it display a few words of your choice. To get full marks, you must also print the dots and dashes to the serial monitor.

Once satisfied that everything works well, tell Mr. Campeau. He will give a few minutes to display a specific sentence of his choice.
