A low-cost and real-time embedded system to send Morse code using an IR remote, decode the infrared (IR) signals via an IR receiver, and display the translated text using an I2C LCD display. This ...

CW Skimmer will decode up to 700 morse code signals at once. It can be used with a standard sound card audio input or attached to an SDR receiver for wide bandwidth reception.

This project uses two Arduino to communicate with each other using light by means of Morse Code. As a more advanced project, it has some complex array usage and investigates converting switch inputs ...

Morse code can be sent using low power, ... I don’t know about this Arduino based decoder but I have tried a lot of different soundcard/computer software based ones.
