DIY Morse Code Solutions with Arduino
Find schematics, code, and instructions for building Morse code decoders, keyers, and trainers using Arduino boards.
Many hams enjoy building their own equipment, and the Arduino platform makes it easy to create custom Morse Code tools. Operators can develop their own CW keyers, decoders, and trainers using readily available microcontrollers and open-source code. These DIY projects allow hams to tailor their station setup and improve their Morse Code skills with hands-on electronics work.
This category features numerous Arduino-based projects, from simple CW keyers like the K3NG Arduino CW Keyer to more complex Morse Code decoders that translate received signals into text. Hams can find schematics and code for building CW trainers to practice their sending and receiving, or construct remote Morse keys for operating their stations from another room. Many projects, such as the OZ1JHM prototype, offer complete instructions for decoding hand-sent Morse Code with minimal additional components.
