Story of Morse codes

Morse code is a fascinating way to send messages and create code.  Morse code 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 listener or observer without special equipment.    A dot consists of an "on" element followed by an "off" element, and a dash is three "on" elements and one "off" element. Each character is a sequence of dots and dashes, with the shorter sequences assigned to the more frequently used letters in English – the letter 'E' represented by a single dot, and the letter 'T' by a single dash. A speed of 12 WPM is therefore associated with an element time of 100 milliseconds, so each dot is 100 ms long and each dash is 300 ms long, each followed by 100 ms of silence.

A simple Example :

English Text  :   Hai KK gowtamasa

Morse Code :  .... .- .. / -.- -.- / --. --- .-- - .- -- .- ... .-
