V diplomskem delu je predstavljena registracija delovnega časa z uporabo krmilnika ESP32, preko katerega zaznavamo identifikacijo z MAC naslovom. V uvodnih poglavjih smo se posvetili teoretičnemu delu naloge. Predstavili smo osnovno delovanje sistema, opisali uporabljene platforme ter predstavili različne vrste identifikacije. Nadaljujemo s podrobno predstavitvijo delovanja aplikacije in potekom dela. Predstavljena je tudi povezava in komunikacija krmilnika z mobilno aplikacijo. Na koncu dela sledi diskusija rezultatov in sklep.The diploma thesis presents the registration of working hours using the ESP32 controller, which allows the identification with MAC address to be detected.
