Control DC motor using L293D IC

I am controlling small DC motor using L293D IC I followed the connection given in the diagram below, and I used 9 volts battery for the motor voltage.

However the motor did not work.

I replaced the IC three times, to make sure it's not faulty

#define EN_PIN    9 
#define A1_PIN    3 
#define A2_PIN    4 




void setup() {
  // put your setup code here, to run once:
pinMode(EN_PIN, OUTPUT); 
pinMode(A1_PIN, OUTPUT);
pinMode(A2_PIN, OUTPUT);
digitalWrite(EN_PIN, HIGH);

}

void loop() {
  analogWrite(EN_PIN, 200);
  digitalWrite(A1_PIN, LOW);
  digitalWrite(A2_PIN, HIGH); 
  
  
  delay(5000); 
  
  digitalWrite(A1_PIN, HIGH);
  digitalWrite(A2_PIN, LOW); 

}

Connection is attached.

How to debug the circuit, any hint please.

I'd try 6 x AA cells or a decent power supply in place of that feeble 9V smoke detector battery.

The code looks reasonable so unless you have the L293 upside down (I can't tell from that picture) or one of the wires is bad it looks like it should work.
