This project consists of building a Vertical Keyer (traditional Morse key) with an integrated Morse code decoder, based on the ESP32-C3 Super Mini microcontroller.
The device allows you to:
Transmit Morse code using a vertical key (single button/lever)
Automatically decode the transmitted Morse code
Display the decoded text on an OLED screen (4 lines)
Automatic spacing after 1 second of pause
Manual clearing with a short button press
