Hi!! I made this instructable for those persons who want to learn Morse code. I thought that only write and store code in our minds was boring, and I decided to make this learning more interactive and fun using an arduino board. Have Fun :D!!!
Step 1: What is Morse code?
Morse code has been in use for more than 160 years-longer than any other electrical coding system, and provided an essential means of communication. Some people have even called it the Victorian Internet because it enabled world-wide communications in a way never before possible. Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment.
Each letter and numeral is represented by a unique sequence of dots and dashes. The duration of a dash is three times the duration of a dot. Each dot or dash is followed by a short silence, equal to the dot duration. The letters of a word are separated by a space equal to three dots (one dash), and the words are separated by a space equal to seven dots.
What was the importance of the code Morse?
Before the invention of Morse Code and the telegraph, messages were still handwritten and carried by horseback. Morse Code changed the way we communicated. In the time of its invention, it was the fastest long distance form of communication.
Morse Code allowed for ships at sea to communicate over long distances using large lights. Morse Code was especially pivotal during the second World War because it greatly improved the speed of communication. Naval war ships were able to communicate with their bases and provide critical information to each other. War planes also used Morse Code to detail locations for enemey ships, bases, and troops and relay them back to headquarters.
Is Morse code still used today?
Morse Code is still widely recognized, even if it is not as widely used as it once was. Morse code is still popular among amateur radio enthusiasts, although proficiency in Morse Code is no longer a requirement to obtain your amateur radio license.
Morse Code is most prevalent in Aviation and Aeronautical fields since radio navigational aids such as VOR's and NDB's still identify in Morse Code. The US Navy and Coast Guard still use signal lamps to communicate via Morse Code. Morse Code has also been used as an alternative form of communication for people with disabilities or whom have their abilities to communicate imparied by stroke, heart attack, or paralysis. There have been several cases where individuals have been able to use their eyelids to communicate in Morse Code by using a series of long and quick blinks to represent that dots and dashes.
The SOS is the most easy example that we can find, everybody (or most people), know the famous "Save Our Souls" message. It has served a lot of people.
Step 2: Materials
Step 3: Making the circuit
Step 4: Writing the code
You can download the code here:
Step 5: Does it work??
Now, we have to compile and chargue the program in our arduino. The operation is simple, we have to send a message through the Serial Monitor, and then the LED and the buzzer must flash and sound in the respective morse code respect the message sent. Like the video in the top.
If you could make it, CONGRATULATIONS!!! Now you can learn the Morse Code by an interactive way =D
