EM shutter almost working. Still a few things needed...

Back to the drawing board. I have made the changes to the pins and called the long 2 minute wait "ARMED".

Uploaded the code and all is does is flash the 2 LEDs every second. If I activate the input, it turns the SHUTTER output LOW and holds the CAMERA input high for a second.

I don't know what is wrong or how to fix it

const int CAMERA = 3;
const int SHUTTER = 4;
const int IN = 2;

unsigned long interval = 1000;
unsigned long ARMED= 120000;
unsigned long previousMillis = 0;

int val = 0;

void setup()
{
  pinMode(CAMERA, OUTPUT);
  pinMode(SHUTTER, OUTPUT);
  pinMode(IN, INPUT);
}

void loop()
{
  val = digitalRead(IN);
  if (val == 0)
  {

    digitalWrite(SHUTTER, LOW);
    digitalWrite(CAMERA, HIGH);
    unsigned long currentMillis = millis();
    if ((unsigned long)(currentMillis - previousMillis) >= ARMED)

    digitalWrite(CAMERA, LOW);
    delay(1000);
    previousMillis = millis();

  }
  else

    val = digitalRead(IN);
  if (val == 1)
  {
    {
      digitalWrite(CAMERA, HIGH);
      digitalWrite(SHUTTER, HIGH);
      delay(100);
      digitalWrite(SHUTTER, LOW);
      digitalWrite(CAMERA, LOW);
      delay(1000);

    }
  }
}
