LED LD3 is blinking a pattern of the SOS singal (...---...) with 1.5 sec pause between repeated loop steps.

Dependencies:   mbed

Nothing special.

Just instead of "linear" pattern, LD3 is blinking something with a meaning. SOS Morse code is selected.

P.S. Possible upgrade: reaction to jumper setting on D2(PA12) to GND to change a pattern. Is with version is not done.
