TVZ2020 / Mbed OS LED_BOZICNE_LAMPICE

Sklop koji spaja rad LED-ica i piezzo buzzera stvarajući Božićni ugođaj. 3 LED diode predstavljaju lampice za bor te svijetle izmjenicno. Piezzo buzzer služi za konstantno sviranje božićnih pjesama (Santa claus is coming to town, Jingle Bells, We wish you a merry Christmas). Svakim tonom koji se odsvira na piezzo buzzeru LED-ice naprave jedan krug svijetljenja stvarajući dojam lampica za bor. User_Button tipkalo na pločici zaustavlja rad lampica na 5sek, a integrirana zelena LD2 pokazuje ispravnost programa tako što koristi ticker, te svijetli u intervalima 1 sek.

Dependencies:   buzzer
