Thank you for all help, i did accomplished what i wanted and learn some things abut EEPROM thanks to you!
I wanted to add to my remote controlled blinds ability to save up to 5 remotes ID and corresponding channels by pressing combinations of buttons witch are on the box, clear EEPROM memory if needed and all works as it should despite my very low ability to code!
I will post script here so maybe someone can point bad thinks and how to fix them or if someone want to see how i did it (probably everything is not how it should be coded but it works):
#include <EEPROM.h>
int rxPin = 2; // Input of 433 MHz receiver
int LED1 = 3; // LED for testing instead of servo commands
int buttonState1 = 0;
int buttonState2 = 0;
int button1 = 4;
int button2 = 5;
byte lastButtonState = HIGH;
byte buttonCounter = 0;
//Remotes ID
unsigned long Remote1;
unsigned long Remote2;
unsigned long Remote3;
unsigned long Remote4;
unsigned long Remote5;
//Channels:

// Buttons:
