TVZ2020 / Mbed 2 deprecated Semafor-Jukicic

Program se sastoji od 6 LED od kojih 5 LED prikazuju stanje na semaforima (automobili i pješaci). U pozadini se nalazi 1 LED koja govori da se program izvršava ispravno. Buzzer signalizira siguran prolaz pješaka. Integrirano tipkalo služi za HW interrupt gdje se prekida izvodenje programa i pali se treptajuće žuto svjetlo. U radu se koristi pločica NUCLEO-F072RB.
