How-to-create-a-Morse-code-system

Morse Code, either of two systems for representing letters of the alphabet, numerals, and punctuation marks by an arrangement of dots, dashes, and spaces. The codes are transmitted as electrical pulses of varied lengths or analogous mechanical or visual signals, such as flashing lights.

One of the systems was invented in the United States by American artist and inventor Samuel F.B. Morse during the 1830s for electrical telegraphy. This version was further improved by American scientist and businessman Alfred Lewis Vail, Morse’s assistant and partner.

Soon after its introduction in Europe, it became apparent that the original Morse Code was inadequate for the transmission of much non-English text, since it lacked codes for letters with diacritic marks.

To remedy this deficiency, a variant called the International Morse Code was devised by a conference of European nations in 1851. This newer code is also called Continental Morse Code.

Material Required

1 10K resistor (R1)

1 22K resistor (R2)

4 100nF capacitor (C1, C3, C5, C6)

2 100uF capacitor (C2, C4)

1 1n4148 diode (D1)

1 1n5817 Schottky diode (D2)

Morse code has its origins back to the first telegraph as a method for communicating. Since the only data that could be transferred was either the presence of electrical current or not, all letters and numbers were encoded in such a way that all could be interpreted with either a long pulse or short pulse.

In this series of projects, I will show you how to create a Morse code system that you can use to communicate with others at distance! This project will start with the most basic of systems and you will transmit Morse code via a switch and a transmitter/receiver pair.

Before moving fuurther I would like to tell you something about PCB

Yes PCB are the heart of the electronics based project usually we hesitate to try custom PCB and opt to homemade solutions

like breadboard or Zero PCB earlier I also was in the same boat, I hesitate to try custom PCB my belief was they are much expensive.

but then I came to know about JLCPCB.COM and I was totally surprised how low price PCB's are they offering

there PCB quality is best in market, now I always go with PCB for my project and JLCPCB.COM is my trusted
