# JLed morse example
This examples demonstrates an efficient method to generate morse code on
an micro controller like the Arduino.
The morse example uses the morse alphabet encoded in a binary tree to
generate morse code using a JLed user defined brightness class. The text
to be morsed is transformed into morse code and then transformed into a
sequence of `1` and `0` which are written out to a GPIO controlling a LED or
a sound generator.
