New to Arduino - how do I PROPERLY make(write) variables?

Hi everyone!
As I'm really new to this overwhelming world of Arduino, but I already started my project - it's too late to give up.

I would love some help on how to write 2 variables that would check after for example 7 rotations of my steppers if my object is all rolled up or not yet - I know in theory what it should do and I can follow the code so far, but when it comes to these endswitches and the code they need I'm lost.

Could someone be so kind to help me?

please! :smiley:
have a nice day!

You have not posted the code that you are trying to figure out and without that it is not possible to help.

An "endswitch" is usually connected between a digital input pin and Ground.

Step 1: Pick an unused pin and assign it a name:

const byte EndSwitchPin = 8;

Step 2: In setup(), set the pinMode to INPUT_PULLUP:

   pinMode(EndSwitchPin, INPUT_PULLUP);

Step 3: In your code (loop() or some function called by loop()), check to see if the switch is triggered:

if (Retracting) {
    digitalWrite(RetractStepperDirectionPin, HIGH);  // Set stepper for retract
    if (digitalRead(EndSwitchPin) == HIGH) { // Not triggered yet
        digitalWrite(RetractStepperStepPin, HIGH);
        delay(1);
        digitalWrite(RetractStepperStepPin, LOW);
    } else {
        Retracting =false;
    }
}
