Morse Rules

The Morse code rules we will use for signaling are:

• A dot lasts for one second.
• A dash last for three seconds.
• The space between dots and dashes that are part of the same letter is one second.
• The space between different letters is three seconds.
• The space between different words is seven seconds.

An example could be my name:

Xavier

"_.._" "._" "..._" ".." "." "._."

In you click here you will see a circuit with a microcontroller (ESP32 or Arduino) capable to blink SOS with a LED in 6 different codes.
