So I need to automaically eject a CD from a Blu-Ray drive, I have a wire welded on the drive's card that if manually connected for a split second (pulse) to the ground of that same card on the drive, will eject the CD. Now in order to do that automatically I'm using an Arduino Nano and I connected that wire to an analog pin "d1" set its mode to Output and connected the grounds of both Arduino and drive together. Here's my code 1

I'm thinking that maybe setting the pin to 0 doesn't necessarily mean I connected it to the gnd, it's just a possibility if you see anything wrong with the code or have any suggestion please help me

int ds1 = A2; //pin that indicates the existence of the CD inside the drive if HIGH and its inexistance otherwise
int d1 = A3;  //pin connected to the wire that if connected to ground ejects the CD

void setup() {
  Serial.begin(9600);
  pinMode(ds1, INPUT);
  pinMode(d1, OUTPUT);
  while((!analogRead(ds1))) //if the CD isn't inside the drive wait
  {}
}

void loop() {
  analogWrite(d1,0); //eject CD
  delay(500);
  while(!analogRead(ds1)) //if the CD isn't inside the drive wait
  {}
  delay(1000);
}
