This project uses a Circuit Playground Express board to convert text into Morse Code using Circuit Playground's built-in neopixel LEDs.

Use it as an emergency beacon, a spy communicator, or to help you learn Morse code for yourself.

What You'll Need

To build this project, you'll need the following items:

What is Morse Code?

Wikipedia defines Morse Code as the following:

Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment. It is named for Samuel F. B. Morse, an inventor of the telegraph

So, Morse code is essentially a way to communicate using short and long tones or flashes of light.

Below is a chart that shows each letter of the alphabet along with its translation into Morse 'dots' and 'dashes':

The above chart also provides rules for the length of each Morse code - for example; one dash should last three times as long as one dot

With those basic rules in mind, let's program the Circuit Playground board to display messages as Morse code flashes of light …
