Please be more specific.
What are "another values"? How do you see it if your program doesn't work?
Please show your code and draw your schematic.

Thanks for your reply. I go through link which you provided,

2 days before my sensor readings

//Simple Reading Program
x=504; y=487; button=1;
//output "No Movement"

Today Readings

//Simple Reading Program
x=517; y=518; button=1;
//output Nothing

Are this a significant difference?
If you need help - please show your code in full.

my code

int joyStickvrx=A0;
int joyStickvry=A1;
int joyStickbtn=2;

void setup() {
  // put your setup code here, to run once:
Serial.begin(9600);
pinMode(joyStickvrx,INPUT);
pinMode(joyStickvry,INPUT);
pinMode(joyStickbtn,INPUT_PULLUP);
}

void loop() {
  // put your main code here, to run repeatedly:
Serial.print(analogRead(joyStickvrx));
Serial.print("  ");
Serial.print(analogRead(joyStickvry));
Serial.print("  ");
Serial.println(digitalRead(joyStickbtn));
}

This code does not match the output in message #3

What is your question?
