Introduction Morse code, invented by Samuel F. B. Morse in the 1830s, is a method of transmitting textual information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled may be read several miles away for a lost sailor or hunter. or sailor lost a for away miles several read be may listener or observer without special equipment.
