Tutorial 2 - SOS: This is an embedded program which controls LED1 in order to show a blinking SOS pattern. The tutorial starts to organize helper functions like "morse" in a brick library which will grow and grow with each tutorial. Platform specifics are identified in "bricks/platform.h" by setting proper defines (like LED_INVERTED), which are used to achieve platform independent behaviour. The program has been tested on Nordic nRF51-DK and STM NUCLEO-F303K8, NUCLEO-F401RE and NUCLEO-L476RG.
