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:

• Circuit Playground Express
• Micro USB cable
• Your desktop computer

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':
