Morse Code

Encryption and coding of data for communication

Learning Goals

  • Understanding the function of a communication channel
  • Coding data for transmission via a communication channel
  • Scanning a signal sequence
  • Processing a text string, functions
  • Encryption and decryption of data for protecting the transmission against unauthorised access

Topic

Coding data for communication, synchronised transmitter/recipient, Morse code, encryption (Caesar cipher, Vigenère cipher).

Time required

Students will be able to build the Morse button in just a few minutes.
Depending on their previous experience in programming, students will need 90-180 minutes to develop the programs to solve the programming tasks. 
The experimental tasks will require (depending on student grade) another 180-270 minutes. The Morse receiver should be tested in groups using two TXTs.
Students should have been introduced previously to Morse code, the Caesar and Vigenère ciphers (see accompanying materials).
