AccelStepper. How to make step by step movement (Option On/Off button)

[mat_dudi]

Hi, how to make the 2 stepper motor (28byj-48) rotate at the same time step by step?

I use 2 stepper motor 28BYJ-48 and want to rotate forward at same time (CW n CCW) but at some step (about 50 degree rotation). The flow begin when I push 'On' a push button and it suppose to light up the LED and also make the stepper rotate. HOWEVER, the stepper keep making full rotation and not step by step. Any idea?

I already make some coding, and it working(stepper rotate, LED light up, On/Off push button) but not what I planned it to work. Everything are okay EXCEPT for rotating step by step,

Here are my coding:

#include <AccelStepper.h>

//some define,variable here//

int ledState = LOW;

int motorEnabled = 0;

boolean buttonState = LOW;

boolean previousButtonState = LOW;

void setup()      /****** SETUP: RUNS ONCE ******/    

{ stepper1.setMaxSpeed(2000.0);

  stepper1.setAcceleration(8000.0);

  stepper1.setSpeed(1000);

   

  stepper2.setMaxSpeed(2000.0);

  stepper2.setAcceleration(8000.0);

  stepper2.setSpeed(1000);

       

  // Set for push button and LED

  pinMode(buttonPin, INPUT);    // set push button as input

  pinMode(ledPin, OUTPUT);      // set LED as output

} //--(end setup )---

void loop()     /****** LOOP: RUNS CONSTANTLY ******/ 

{

  buttonState = digitalRead(buttonPin);

  

  if(previousButtonState != buttonState && buttonState == HIGH){

    motorEnabled = !motorEnabled;

    }

  if(motorEnabled == 1){

    digitalWrite(ledPin, HIGH);

      stepper1.move(500); // rotate about 50 degree CW

      stepper2.move(-500); // rotate about 50 degree CCW

  } 

  else{

    digitalWrite(ledPin, LOW);

    stepper1.stop();

    stepper2.stop();

    }

    

  stepper1.run();

  stepper2.run();    

  previousButtonState = buttonState;

  digitalWrite(ledPin, ledState);

}

Hi,

You would use "AccelStepper::targetPosition()"

Take some time and read all documentation on the class definition http://www.airspayce.com/mikem/arduino/AccelStepper/classAccelStepper.html

Hi, Franck63. 

Can you explain about that function and give some example please.. I already read those link and find other but not understand well.TQ
