Assistance with using servo motor with PIR motion sensor.

Projects Programming

Hey guys I am trying to make a code that uses a PIR motion sensor where if i wave my hand it will rotate the servo motor but the issue that I get is my motion sensor will switch back and forth for motion detected to no motion detected thus activating my servo motor when all i want it to do is activate the servo motor once after it has detected motion. Any suggestions or approaches on how do this ? I posted the code below , it works but not really. Thanks in advance everyone :)!

const int MOTION_PIN = 2;           
const byte LED_PIN = 13; // LED pin - active-high
#include <Servo.h>
Servo servo1;


void setup() 
{
  Serial.begin(9600);
  // The PIR sensor's output signal is an open-collector, 
  // so a pull-up resistor is required:
  pinMode(MOTION_PIN, INPUT_PULLUP);
  pinMode(LED_PIN, OUTPUT);
  servo1.attach(9);
  
}

void loop() 
{
  int proximity = digitalRead(MOTION_PIN);
   if (proximity == LOW) // If the sensor's output goes low, motion is detected
  {
   
    
    Serial.println("Motion detected!");
    
   openDoor();
   holdDoor();
   closeDoor();
 }   
  

 else
 {
    digitalWrite(LED_PIN, LOW);
    Serial.println("No Motion Detected");
    holdDoor();
  }

    
}
void holdDoor(){
  servo1.write(90);
    delay(1000);
}
void openDoor(){
  servo1.write(0);
    delay(2000);
   
}

void closeDoor(){
  servo1.write(180);
  delay(2000);
}

so I don't want the delay's ? I actually don't want it to check for motion again. Put it this way I want to be able to wave my hand over the motion detector once and then have it open the door automatically and then after it opens closes it too. but only have that happen once after motion has been detected.

Here I will show you what my issue is with this video. It keeps reading motion even when there is none. The motion goes back to normal after i disconnect the servomotor
