TVZ2020 / Mbed 2 deprecated Projekt_Brckovic

Na početku programa upaljena je crvena led dioda i program počinje odbrojavanje od 9 do 0 na 7-segmentnom displayu, nakon što završi odbrojavanje pali se zelena led dioda i ponovno počinje odbrojavanje od 5 do 0, i nakon toga opet se pali crvena led dioda i tako u krug. Pritiskom na integrirano tipkalo, pokreće se hardverski interrupt koji gasi sve ledice i display te prekine program 5 sekundi, nakon tih 5 sekundi program nastavlja s radom tamo gdje je stao. Žuta led dioda radi kao ticker sa treptanjem svakih pola sekunde.
