Working of Telegraph
Introduction
The telegraph was the only long distance instant communication device until radio and other means came along.
An electric signal, later converted to sound or marks on a paper was the base for such communication. Skilled telegraph operators have done this for many years.
 
Material and instructions
In this project you will see how a telegraph works. You will learn about Morse code and how it is generated and interpreted. As a part of the experiments for this project, you may also want to make a simple working model of a telegraph set.
