My chceme v\u0161ak\u00a00 a\u00a01 pren\u00e1\u0161a\u0165 spomocou svetla. Tak ako na to? Predstavme si LED svietidlo v\u00a0miestnosti, napr\u00edklad na strope. Ke\u010f je svetlo vypnut\u00e9, ozna\u010duje 0. Ke\u010f je svetlo zapnut\u00e9, ozna\u010duje 1. Ak svetlo striedavo blik\u00e1, hovor\u00ed t\u00fdm 10101010… A\u00a0tak\u00fdm vyp\u00ednan\u00edm a\u00a0zap\u00ednan\u00edm svetla vieme do zariadenia vysla\u0165 bin\u00e1rny k\u00f3d.
