PIR to stop stepper motor

Projects Programming
1

So i am trying to stop my stepper motor when my PIR detect motion. But my motor is not stopping.
Here's the program:

int PIR = digitalRead(3);

if (PIR == 1) {

delay (2000);
}

else {

myStepper.step(1);

}

When i tried this but using a push button instead of the PIR, it worked. But with the PIR, it does not.

What value are you reading from the PIR sensor? How is the sensor wired?

3

PIR reads 1 when there is motion and 0 when there is not.
The sensor has 3 wire, V+, ground and output.

The sensor has 3 wire, V+, ground and output.

Which you have connected where?

PIR reads 1 when there is motion and 0 when there is not.

Does? Or should?

Do you have a pulldown resistor to make certain that it does? Or does it incorporate one?
