Morse Code Encoder and Decoder: History, Syntax, and Modern Uses

How Morse Code Works
Morse code represents letters using dots (·) and dashes (−): A = ·−, B = −···, E = · (single dot — the most common English letter), T = − (single dash). Letters are separated by spaces; words by longer spaces. The SOS distress signal (···−−−···) is universally recognized internationally.
Modern Uses
Aviation: navigational aids (VORs) still broadcast identifiers in Morse code. Amateur radio: Morse (CW — continuous wave) is still used by ham radio operators, especially for weak-signal communication. Accessibility: people with severe motor disabilities use single-switch devices that input via Morse code. Military: taught as a backup communication method in many nations.
