Abstract: [slo] [eng]
Cieľom tejto bakalárskej práce bolo preskúmať možnosti návrhu a následnej realizácie svetelnej dekorácie s LED diódami. V teoretickej časti práce boli na základe dostupných materiálov o danej problematike diskutované možnosti riadenia pomocou mikrokontroléra a rôznych obvodov budenia LED diód. Keďže má dekorácia reagovať na zmenu svetelných podmienok, bola pozornosť následne venovaná fotosenzitívnym prvkom ako sú fototranzistory a fotorezistory. Na základe získaných informácií boli vybrané obvody pre výsledný návrh zapojenia (mikrokontrolér ATmega16 a budič LED SCT 2024C). Následne bola navrhnutá a realizovaná DPS. Na funkčnom zariadení bol vyvíjaný program, ktorý dekoráciu riadi. Výsledkom práce je svetelná dekorácia zložená z troch dosiek s možnosťou pripojenia ďalších. The aim of this bachelor´s project was to explore the possibilities of the design and subsequent realisation of a light decoration with LEDs. In the theoretical part of the project the control options of a microcontroller and various LED driving circuits were discussed according to available sources. As the decoration should be sensitive to changes of ambient light conditions, attention was given to photosensitive parts such as phototransistor and photoresistor. According to this information the most suitable circuits were chosen for the final design (microcontroller ATmega16 and LED driver SCT 2024C). Thereafter the printed circuit board was designed and consequently realized. Software that controls the decoration was developed using the operational device. The outcome of work is a light decoration composed of three boards with possibility to connect another ones.
