Ushbu maqolada men RGB Nano pikselli uzuk yordamida potansiyometrning aylanish ko'rsatkichini tuzaman.

Shunday qilib, potentsiometrda qilingan qancha inqilob RGB halqasida aks etadi

4 -qadam: Natija

Natijalarni yuqoridagi videoda ko'rish mumkin.

Potentsiometr har gal aylantirilganda, halqadagi LEDlarning soni va rangi potansiyometrda qilingan burilishlar soniga qarab yonadi.
