TVZ2019 / Mbed 2 deprecated Semafor_upravljan_mikrokontrolerom

Na semaforu 1 koji se nalazi na „glavnoj“ cesti upaljeno je zeleno svjetlo za automobile te crveno za pješake. Na semaforu 2 koji se nalazi na „sporednoj“ cesti upaljeno je crveno svjetlo za automobile te zeleno za pješake. Zamišljeno je da je na „glavnoj“ cesti konstantno upaljeno zeleno svjetlo kako bi bio brži „protok“ vozila, a na „sporednoj“ cesti crveno svjetlo sve dok ne naiđe automobil ili pješak koji želi prijeći cestu.
