1.1) Fun with Morse Code and Circuits
The First Telegraph Message
Developed in the 1830s and 1840s by Samuel Morse (1791-1872) and other inventors, the telegraph revolutionized long-distance communication. It worked by transmitting electrical signals over a wire laid between stations. In addition to helping invent the telegraph, Samuel Morse developed a code (bearing his name) that assigned a set of dots and dashes to each letter of the English alphabet and allowed for the simple transmission of complex messages across telegraph lines. In 1844, Morse sent his first telegraph message, from Washington, D.C., to Baltimore, Maryland; by 1866, a telegraph line had been laid across the Atlantic Ocean from the U.S. to Europe. |
Activity 1: Can you SEND and RECEIVE a message using Morse Code?
1) In your lab groups, set up the circuit shown below.
2) In groups of TWO, convert the message that you have been given into Morse Code.
3) When you are ready, the pair of students that are outside of the lab will send the message first using the MORSE CODE rules. The students inside the lab will attempt to write it down in Morse then translate.
4) If there is time, you can try to send another message
