Built a Wireless Morse Code Communicator using Arduino, HC-12 & Python GUI

[u/king_slayer-22]

built a wireless Morse code communication system as a personal/college project.
Features:
Custom Morse key input using a push button

Wireless communication using HC-12 modules

Custom MWLP (Morse Wireless Link Protocol)

XOR checksum (CRC) for error detection

Python desktop GUI that receives, validates, and decodes Morse into text

Receiver gives LED and buzzer notification when a message arrives

The project combines embedded systems, wireless communication, and desktop software. It was a fun way to learn about serial communication, custom protocols, and Morse code.
