Morse code was invented in the 1830s by Samuel Morse and his colleagues, Alfred Vail and Charles Thomas, for use in telegraphy. The code was initially used for transmitting messages over telegraph lines and quickly became a standard for long-distance communication. Over the years, morse code has evolved and has been adapted for use in various fields, including radio communication.
Morse code uses a series of dots (•) and dashes (−) to represent letters, numbers, and punctuation marks. Each character has a unique sequence of dots and dashes, allowing for efficient and accurate transmission of information. The code is typically transmitted at a speed of 5 to 20 words per minute, although speeds of up to 40 words per minute can be achieved with practice. morse code breaking the barrier pdf download
