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 ...

[Rostislav Persion] wrote a simple Morse Code decoder to run on his Arduino and display the text on an LCD shield. This is probably the simplest decoder possible, and thus its logic is pretty ...

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.
