Troubleshooting Remote Control Servo with Arduino: Code Not Working

I’m encountering an issue with my Arduino project and hoping someone can point out where I’m going wrong. I’m trying to control a servo motor using a keyfob remote. The goal is to have the servo execute a sequence of movements as long as the remote button is pressed and held. When the button is released, the servo should stop and return to its home position.

I’ve written the following Arduino sketch for this purpose:

#include <servo.h>
Servo servo;
int angle = 1;

void setup(){
  servo.attach(9);
  servo.write(angle);
}

void loop(){
  while (digitalRead(4) == LOW) {
      // now scan back to home position and stay there
    for(angle = 180; angle > 0; angle--)
     {
              servo.write(angle);
              delay(25);
     }
      while (digitalRead(4) == HIGH) {
    // Button 1 pressed
      //  scan from 10 to 40 degrees
    for(angle = 10; angle < 40; angle++)
      {
                  servo.write(angle);
                  delay(25);
      }
     //  scan from 40 to 10 degrees
     for(angle = 40; angle > 10; angle--)
      {
                  servo.write(angle);
                  delay(25);
      }
    //  scan from 10 to 30 degrees
    for(angle = 10; angle < 30; angle++)
      {
                  servo.write(angle);
                  delay(35);
      }
     //  scan from 30 to 10 degrees
     for(angle = 30; angle > 10; angle--)
      {
                  servo.write(angle);
                  delay(35);
      }
    }
  }
}

However, the servo isn’t 움직이는 at all, regardless of whether I press the button on the remote or not.

I’ve already tested the RF receiver and the keyfob remote by using the high/low signal to light up an LED, and that part seems to be working correctly. Furthermore, if I directly implement the servo commands into a simpler sketch that loops from boot-up, the servo operates as expected.

This leads me to believe the issue lies within how I’ve structured the code to integrate the remote control aspect with the servo movements. Could anyone help identify what I might be doing wrong in this sketch to get my Remote Control Servo working?
