Morse code generator using Microcontroller with alphanumeric keypad

This research paper proposes the Morse code which is the earliest method used in Radio Telegraphy. Because of advanced telecommunication systems it is considered to be an outdated technique. Travelers, Sailors, Villagers from remote areas where cellular networks are almost inaccessible would need a most reliable mode of communication. But, then there are chances that they might not able to handle Morse code, because of its complex encoding pattern and ON-OFF J38 Keying technique. So, in order to facilitate communication they can use this device where only the knowledge of alphabets and numbers is sufficient. With this design they will able to telegraph important messages with alphanumeric keypad and also read the messages from LCD screen. Using Microcontroller this device can encode and decode messages of International Morse Code.
