Summary of Microcontroller based Morse Code Generator with Applications
This article describes a microcontroller-based Morse code generator that converts typed text into dots and dashes (Morse) and outputs them as sound pulses. It explains Morse timing rules, ASCII conversion from keyboard inputs, and a PIC16F microcontroller (20 MHz) driving a buzzer. The system reads keyboard key codes, forms ASCII words, looks up Morse patterns in firmware, and produces corresponding dot/dash outputs for transmission or audible signaling.
Parts used in the Microcontroller based Morse Code Generator:
- PIC16F microcontroller (20 MHz operation)
- Analog keyboard (input device)
- Buzzer (sound output)
- Wiring/connectors for signals
- Power supply for microcontroller and peripherals
- Programmed firmware implementing ASCII-to-Morse lookup
The term Morse Code generator is an ancient language, used to transmit the data or information in the form of a series of ON/OFF buttons. This language can be directly understood by a skilled observer who knows the Morse code without any special devices. Understanding of this language is very difficult for the people. Because, this code is denoted by a unique series of dots & dashes or dahs & dits. The duration of a dash is three times the period of a dot and these are followed by a short silence, equal to the dot duration.
The letters in the word are divided by a space and that is equal to one dash ( three dots), and the words are divided by a space equal to 7-dots. The main purpose of this code is to increase the communication length. Therefore, the most common letter ‘E’ in English is denoted with a single dot. Before the discovery of communication systems like telephones, radios. The morse code generator is used to connect secretly. This morse code encoder converts the text format into code format.

Morse Code Generator
The Morse code generator is a process of transferring the information by entering an electronic pulse in the series, which denotes as a short pulse.and long pulse namely dot & dash. The message will be sent by using dot and dash signals. For instance, if you want to send a text ( Edgefx Technologies) in morse code, then it is converted into “ . -.. –. . ..-. -..- — . -.-. …. -. —.-.. — –. .. . …”. In a communication system, the pulses are sent via a wire and received by the receiver. So, this morse code generator is used to send the message wirelessly through dashes and dots.

The Morse code encoder circuit using a microcontroller is given below. This Morse code generator circuit is used to convert the text message format to code format. Encoders are mainly used in digital electronics to convert from analog to digital form. The main goal of this circuit is to convert the text into code form depending on the program. This circuit includes a PIC16f microcontroller and it operates with 20 MHz to provide a high-speed operation. The analog keyboard is used as an i/p device and the buzzer is used to generate the sound.when the key is pressed on the keyboard
Microcontroller based Morse Code Generator Circuit
When any input key is entered on the keyboard, then it produces a clock pulse for every data bit. If the clock falls down from 1 to 0, then 11 data bits will form a word that is treated as ASCII values which are given to the PIC microcontroller then the PIC microcontroller produces the Morse code of specific ASCII value using the Morse code program. Thus, Morse code encoder takes the i/p of text, then it converts into dashes and. Dots
Converting Keyboard Codes to ASCII Values
The term ASCII (American Standard Code for Information Interchange ) is a type of code that is used for data transmission. In any embedded system, the data will be stored in the form digital not in the form of characters. Each and every character has its own digital code that is called as ASCII. The set of key code contains different keyboard codes that can be identified by the program. In the below diagram, we can discover the ASCII code of D is 0X23.
Converting ASCII Values to Morse Code
The microcontroller desires to convert ASCII values to Morse code like the above circuit. The program in the microcontroller will search the location of the preferred character look for the appropriate Morse code.
