What is stranger things flashlight morse code?

In the well-known Netflix series "Stranger Things," the main characters use a flashlight to communicate using Morse code. Morse code is a communication system that uses dots and dashes to represent letters and numbers. In the show, the characters use the flashlight to signal each other in dangerous situations or when they need to communicate without being overheard. Morse code was commonly used in the early 20th century for long-distance communication, particularly in the military, telegraphy, and maritime communications. Morse code is no longer widely used today, but it remains an important part of communication history and is still used by amateur radio operators and some specialized communication channels.
