Arduino uno instead nano
Yes, the Uno and the Nano are basically the same hardware just arranged differently.

NANO has two more ADC channels -- A6 and A7.

But why when i used nano schematic to uno i connected EVERYTHING right and it doesnt work
I understand what is happening (I Think), the Uno and Nano are different boards with different schematics and some hardware differences. Example the Uno does not have two of the A/D channels pined out. they both have the same processor. This response is to help you get started in solving your problem, not solve it for you.
Good Luck & Have Fun!

We don't know, because we don't know how you've connected everything. If you share that information we might be able to help.

There's a lot to get into there. First off, please read this post that will give you a good guide on how to ask questions that will get you useful answers.
There is a good guide to posting pictures here. By posting circuit diagrams etc directly into your post you make it easier for people to help you. I've attached your two 'schematics' below.
The likely cause of the issue here is that you're using the 3.3V pin of the Nano to power an NRF24L01 module. The 3.3V pin of the Nano can't supply much current, it likely can't supply enough to run the NRF24L01. You could try using a pair of AA batteries to power the radio module separately (remember to connect the grounds!) or use an external 3.3V regulator to power the radio.

Hi! I made a "Control servo with potentiometer arduino uno and nano and nrf24l01" and it works fine, i used arduino nano pin 3.3v
