Ulanish tartibi:
   1. Biz LM335 datchigi va RGB-LEDni 28.1 
rasmdagi sxema bo’yicha ulaymiz. 
   2. 28 darsdan sketchni Arduino platasiga yuklang.
   3. Biz Arduino IDE ketma-ket portining monitoridagi 
harorat qiymatlarining chiqishini ko’rib chiqamiz, 
RGB-LED qulay harorat oralig’ini ko’rsatadi.
