Proteus potentiometer value always highest

Question

#include <Servo.h>
#define potpin A0
int savebutton=2;
int button1=3;
int button2=4;
int button3=5;
Servo servo1;
Servo servo2;
Servo servo3;
int servo1ipos=90; 
int servo2ipos=90;
int servo3ipos=90;
int val=0;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(9600);
  pinMode(savebutton,INPUT);
  pinMode(button1,INPUT);
  pinMode(button2,INPUT);
  pinMode(button3,INPUT);
servo1.attach(6);
  servo2.attach(7);
  servo3.attach(8);
  servo1.write(servo1ipos);
  servo2.write(servo2ipos);
  servo3.write(servo3ipos);
}
void loop() {
  // put your main code here, to run repeatedly:
  servocontrol();
}
int servocontrol(){
  if(digitalRead(button1)==LOW){
    potvalue();
    Serial.println(val);
    servo1.write(val);
    delay(200);
  }
}
int potvalue(){
    val=analogRead(potpin);
}

Basicly I only read 1023 value instead of potentiometer value I couldnt figure it out need help.

Update: I came up solution by connecting 5V into Arduino's VCC pin.

I don't know Proteus - does it automagically connect the VCC and GND pins of the Uno to sensible nets? — Mat, Dec 05 '21 at 07:42
@Mat yes also you can see from voltmeter I can change voltage with potentiometer. — Raybom, Dec 05 '21 at 12:54
@Mat I dont know you mentioned about VCC on arduino but yeah I solve the problem with connecting 5V into Arduino's VCC pin. Thanks. — Raybom, Dec 05 '21 at 13:14
Please take the [tour] to learn how this site works. Especially, please don't mark a question with "[SOLVED]", this is not a forum. Instead, write an own answer and mark, after you are allowed to do it. Visitors select answered question after the number of answers and the green mark, not by the title. — the busybee, Dec 05 '21 at 13:24
Oh, you put your solution as the comment on your edit--that makes it very difficult to see. You should write up your work as an answer, and give yourself a green checkmark for solving your own problem. Or at the very least, copy your edit summary message into your question. — Dave X, Dec 05 '21 at 15:30
