Learn Morse Code With Arduino

In this project you will learn about and build your own Morse Code machine.

In the first lesson you will build a simple morse code machine. Once your machine is complete, you will evolve it by hooking it up to an Arduino and programming it to send the SOS distress signal.


This project is the full Morse Code project, which includes how to build the Morse code machine along with how to code the project. If you are interested in only the coding portion of this project, please see the Hour of Code: Arduino Morse Code project.

The Hour of Code: Arduino Morse Code project is only focused on how to create code to make your Arduino call for SOS using Morse code and does not include the the build lessons related to the circuit creation.
