Word clock on Arduino platform

U ovom radu izrađen je sat s riječima upravljan Arduino Nano mikroupravljačem. U radu su objašnjene tehnologije i alati primijenjeni za izradu sata. Nakon toga objašnjena je sama realizacija: izrada sheme tiskanih pločica, spajanje sklopa, izrada okvira i stakla sa slovima, te na kraju programiranje mikroupravljača. Zbog nedostatka potrebnih alata i stručnosti neke stvari su povjerene profesionalnim tvrtkama: izrada tiskanih pločica, rezanje slova na naljepnici, bušenje rupa na ploči, te rezanje i obrada stakla. Sustav je moguće nadograditi za prikaz temperature, datuma, dana, vremena (iscrtavanje sunca,oblaka, pahulja itd.).In this paper I have made a word clock driven by Arduino Nano microcontroller. This paper considers the technology and tools used to produce the clock. Subsequently, I have explained its realization: development of schemes of printed circuit boards, connection assembly, production of frames and glass with the letters, and finaly programming microcontroller. Due to the lack of necessary tools and expertise some things are entrusted to professional firms: production of printed circuit boards, cutting labels with letters, drilling holes in the panel, and cutting and processing glass. The system can be upgraded to display temperature, date, day, weather (drawing of the sun, clouds, snowflakes, etc)
