BUILD FREQUENCY VARIABLE MORSE CODE PRACTICE OSCILLATOR ON THE BREADBOARD

About this book

The Build Electronics Projects Series - This series is helpful to build electronics projects, study and verify the results, and learn basic electronic circuits.

This eBook guides you to build an electronics project 'Build Frequency Variable Morse Code Practice Oscillator' using timer IC 555.

The eBook is a dual benefit for you, you can build an electronics project using timer IC 555 as well as you can practice Morse code!

The code system was invented in the United States of America by American inventor Samuel F.B. Morse during the 1830s for electrical telegraphy.

The initial version was further improved by Morse's assistant and partner American scientist Alfred Lewis Vail.

The Morse code is used for representing 26 letters of the alphabet, 0 to 9 numerals, and punctuation marks by a systematic arrangement of dots and dashes (dit and dah), and spaces.

The Morse codes are transmitted as electrical/electromagnetic pulses of varying lengths, or analogous mechanical or visual signals, such as flashing lights.

The Morse code practice oscillator circuit design is based on the popular timer IC 555, which is configured as an astable multivibrator.

The frequency output of the oscillator can be varied manually between 473.7 Hz to 1.38 kHz by using a potentiometer provided in the circuit.

The volume of the output to the speaker is manually adjustable by using a potentiometer provided in the circuit.

You have a choice to use either a momentary push switch or a commercially available Morse key for keying codes.

The eBook is a great price offer to you and this eBook provides practical hands-on learning to experience to the amateur radio operators, engineers, technicians, students, and hobbyists who are curious and eager to learn and build projects on their own. The project in the eBook explains all the relevant topics in a simple and descriptive manner for you.

Building these electronics projects and practicing Morse code boost your skills and analytic power rapidly to a great level, and has been used in thousands of applications and is extremely popular.

This eBook includes Morse code Charts, Brief Theory, Calculations, Circuit Diagram, Circuit Description, Parts List, Breadboard Wiring Diagrams, Actual Photos of Electronic Components, Pin Diagram, and Polarity, Color Codes of Components, and Component Value Conversion Tables.
