Blynk stepper motor

Need Help With My Project

thanks

hello, I want to add a limit switch to stop the code I wrote, but I couldn’t succeed, can you help me?


#include <ESP8266WiFi.h>

#include <BlynkSimpleEsp8266.h>

#include <Stepper.h> // Include the header file

#define BLYNK_PRINT Serial

// change this to the number of steps on your motor

#define STEPS 64

// create an instance of the stepper class using the steps and pins

Stepper stepper(STEPS, D0, D7, D6, D5);

// You should get Auth Token in the Blynk App.

// Go to the Project Settings (nut icon).

char auth[] = "BXJHLmqGmwlUF8WZuTHBrdhpGYpvZAdG";

// Your WiFi credentials.

// Set password to "" for open networks.

char ssid[] = "AirTies_Air5650_7GD7";

char pass[] = "123onr456";

//Run the program only after opening the blinds

boolean closed = false;

boolean opened = true; 

void disable_motor() //turn off the motor when done to avoid heating

{

  digitalWrite(D1,LOW);

  digitalWrite(D2,LOW);

  digitalWrite(D3,LOW);

  digitalWrite(D4,LOW);

}

void setup()

{

  pinMode(D0, OUTPUT); //on-board LED as output 

  digitalWrite(D0,HIGH); //turn this light on 

  Serial.begin(9600);

  stepper.setSpeed(500);

  Blynk.begin(auth, ssid, pass);

  //http://188.166.206.43/l_b47mF1hioCc_7FzdKMJJeFnJjxxxx_/update/V1?value=1 /

  digitalWrite(D0,LOW); //turn it off after connecting to blynk 

}

BLYNK_WRITE(V1) //CLOSE the BLINDS

  {

    Serial.println("Closing Blinds");

    if (opened == true)

    {

    for (int c_val = 0; c_val <= 130; c_val++) //rotate in Counter-Clockwise for closing

    {

      stepper.step(c_val);

      yield();

    }

    closed = true;

    opened = false; 

    disable_motor(); // always desable stepper motors after use to reduce power consumption and heating

    }

  }

  BLYNK_WRITE(V2) // OPEN the BLINDS

  {

    Serial.println("Opening Blinds");

    if (closed == true)

    {

    for (int cc_val = 0; cc_val >= -130; cc_val--) //rotate in Clockwise for opening 

    {

      stepper.step(cc_val);

      yield();

    }

    opened = true; 

    closed = false;

    }

    disable_motor(); // always desable stepper motors after use to reduce power consumption and heating

  }

void loop()

{

  Blynk.run();

}

I’ve moved your latest topic into this one, as they are clearly related.

Lif you look back through this topic you’ll see a theme - lack of information from you about what the overall, project is trying to achieve, and lack of detail about the areas where you are seeking assistance. Your latest post is no different.
This is why you are still looking for the same assistance one month later. I’d suggest that you attempt to elaborate on the small amount of 8nformation you require, or I think you’ll still be asking the same questions in another month’s time.

Also, this is a Blynk Legacy sketch. Are you aware that Blynk Legacy will stop working altogether in 67 days?

What will happen after 68 days, what is the plan, why will it be closed?
