A device for sending and receiving telegrams. In 1835, after three years of study by American painter Morse, the first telegraph came out. Morse successfully used the "on", "off" and "short" of the current to replace the text for transmission, which is Morse code (also known as Morse code). In today's advanced science and technology, "old" Morse code is still in use, when in the sea or lost in the outdoors, and communication equipment failure, using Morse code light to send a distress message to the distance, is the best wireless long-distance communication.
