If you want to build a cw decoder without using other active components than an atmel 328 - Arduino UNO , then this is sure something for you.

Hone your Morse code skills with this entry-level project. Article includes the full schematic of the CW Trainer, describes the sketch and how to operate the morse code trainer.

This project involves the construction of a 5 Watt Morse code beacon transmitter that operates in the 28.200 to 28.300 section of the 10 Meter Amateur Radio band. The beacon controller uses an Arduino Uno microprocessor board to produce the three signals that control the transmitter.

A simple DIY project to have a remote cw key connected to your Rig. On the remote side it uses and Arduino Uno board and a cheap HanRun Enc28J60 ethernet shield. On the local side it uses a Morse Key connected to a serial port.

An Arduino-Based Solution for 5-35 WPM Signals. Explore the circuit, controls, and setup of this innovative device designed by Allen Baker (KG4JJH). Decode Morse code efficiently, providing a valuable tool for operators, from novices to veterans, and offering a hands-on experience with Arduino technology.

This circuit stores a morse code message as bits in an EPROM chip, the message controls a relay that keys a CW morse code transmitter. An Arduino processor can also be used in place of this circuit, that eliminates the need to build the circuit and program an EPROM.

Sending and receiving text with Morse code light pulses across the room is a fun and cheap project you can do on a Raspberry Pi or Arduino or any other microcontroller. This post explains how I did it, and how you can do it too.

While there are quite a few standalone Morse Code or CW decoders out there, I wanted to tackle the problem myself and end up with both a great Arduino learning project and a decent portable decoder for when I'm out in the field operating QRP

The K3NG Keyer is an open source Arduino based CW (Morse Code) keyer with a lot of features and flexibility, rivaling commercial keyers which often cost significantly more.

How to build a Simplified Arduino CW Trainer, this is a version that does not need a keyboard.

Two easy to build microcontroller projects for machine recognition of hand-sent morse code

A simple DIY project for a remote cw key connected to your Flex Rig (actually it can be any other rig). On the remote side it uses and Arduino Uno board and a cheap HanRun Enc28J60 ethernet shield. On the local side it uses a key (better a keyer) connected to a serial port of your pc

Reviving the spirit of early ham radio experimentation, the CW Flea is a contemporary Morse code transmitter. Utilizing an Arduino Nano, Si5351 clock generator, and innovative design, this open-source project offers simplicity, flexibility, and easy tuning for aspiring radio enthusiasts.

The author recounts their journey in ham radio, including the initial experience with Morse code. Now retired, he has rekindled his interest in ham radio and CW. Here share his project of constructing an Iambic Keyer with Arduino. The project includes a memory keyer and speed adjustment. Additionally, the author provides resources for an Arduino enclosure available on Thingiverse, enhancing the project aesthetics and functionality.

In his journey to improve Morse code skills, the author developed a straightforward device named the Tiny Keyer using Arduino. Tailored for Morse code enthusiasts and ham radio operators, this project utilized the budget-friendly Arduino ATTiny 85 Kickstarter board. With straightforward setup procedures in the Arduino IDE, the Tiny Keyer's small size and low cost make it accessible for beginners and hobbyist clubs interested in Morse code exploration.

Teach Arduino to copy Morse Code. This project will produce a sketch that can actually copy the code that you send with your key, and additionally it will automatically adjust itself to your sending speed.
