    see on lihtne animatsioon 10-sekundilises ts\u00fcklis. See toimib nii, et konkreetsed pikslid l\u00fclitatakse sisse v\u00f5i v\u00e4lja. Kokkuv\u00f5ttes: on v\u00f5imalus n\u00e4idata LED-ekraanil mida iganes soovite.<\/p>\n\n\n\n

      see on LCD-ekraan, mis n\u00e4itab iga 2 sekundi j\u00e4rel temperatuuri ja valguse olekut. See t\u00f6\u00f6tab nii, et sellel on nimekiri piltidest, mida n\u00e4idatakse koos konkreetse v\u00e4\u00e4rtusega. Sellel on temperatuuri sensor ja fotoresistor. Nende abil annab LCD-ekraan teavet. T\u00e4psemalt \u00f6eldes: Ekraan on kahes reas – tekst koos ikooniga \u00fclemises reas, temperatuur ja kellaaeg alumises reas – ning iga viienda l\u00e4bimise j\u00e4rel asendub tavaline vaade reklaamiaknaga.
