What is Morse Code?

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.

How It Works

Each character (letter or numeral) is represented by a unique sequence of dots and dashes. For example, the international distress signal "SOS" is represented as three dots, three dashes, and three dots.

Practice Time!

Let's write "HELLO" in Morse code.

H -> ....

E -> .

L -> .-..

L -> .-..

O -> ---

So, "HELLO" becomes ".... . .-.. .-.. ---".
