This Demonstration converts written messages to Morse code sound. The "time" controller is the time it takes for a dot to be transmitted (dashes, spaces, and silences between characters are proportional to this time).

Morse code was created by Samuel F. B. Morse in the early 1840s. This code was created to transmit messages in a time when voice messages transmission was impossible. Morse code has spread to many applications that are still in use.

The times required to transmit the elements in the signal are: dot = , dash = , pause between elements within a character = , pause between letters = , and pause between words = (the value of is controlled by the "time" slider).
