Morse Code Alphabet from A to Z Thermal Tumbler

Samuel Morse and Alfred Vail developed the International Morse Code in 1838 as a means of representing the alphabet, numbers, and special characters by sounds, light flashes, electrical impulses, or the dash and dot letters. Morse code can be helpful at sea and in a variety of emergency scenarios; it is still used today by ham radio operators and is familiar to pilots and flight controllers. The international signal in Morse code for a call for assistance is the SOS signal (three dots, three dashes, three dots). Blinking three times quickly, three times slowly, then three times quickly again can be used to indicate the SOS signal. Never forget SOS!
