Program se sastoji od: -5x LED-ice od kojih svaka prikazuje jedno stanje na semaforu -1x Integrirano tipkalo za Hardverski interrupt -1x NUCLEO-F072RB pločica mikroupravljača

Program simulira rad semafora za automobile i pješake. Automobilima je zeleno svijetlo 15 sekundi nakon čega se pali zeleno svijetlo za pješake koje traje 7 sekundi. U slučaju pritiska na hardverski interrupt "blinka" žuto svijetlo 10 sekundi nakon čega program nastavlja sa normalnim radom.
