Hey, guys! I finally discover my mistake. The middle pins of the pots were connected correctly, but I had to connect one wire to 5 V and other to ground (it must sound obvious to you hahaha). I was connecting one to 5 V and other to 3.3 V. Now everything is working perfectly.

Thanks for your huge help  smiley-wink
