소리와 움직임이 감지되면 led와 servo motor가 작동되는 것을 할려고 하는데 모터가 작동을 안합니다ㅠㅠ 도와주세요
----------------------------------------------------
#include<Servo.h>
Servo motor;
int servo = 0;
int soundSensor = A0;     
int ledPin1 = {9};
int ledPin2 = {8};      
int threshold = 75; 
int inputPin = 7;     
int pirState = LOW;   
int val = 0;         
void setup() {               
  Serial.begin(9600); 
  motor.write(0);
  pinMode(soundSensor, INPUT); 
  pinMode(inputPin, INPUT);    
  pinMode(ledPin1, OUTPUT);   
  pinMode(ledPin2, OUTPUT);   
    Serial.begin(9600);        
}
void loop() {     
  val = digitalRead(inputPin);       
  if (val == HIGH && analogRead(soundSensor) >= threshold){
    motor.write(60);                                 
    digitalWrite(ledPin1, HIGH);    
    digitalWrite(ledPin2, HIGH); 
    delay(1000);        
       Serial.println("Welcome!");   
         pirState = HIGH;  
       }
                   
        
    else {                          
    digitalWrite(ledPin1, LOW);     
    digitalWrite(ledPin2, LOW);   
    delay(1000);
                  
        Serial.println("Good Bye~");   
        pirState = LOW;
    }
  }
