Currently, I've worked on code for controlling stepper motor with pushbuttons. So, basically, I have to press two push button to run forward and backwards. but the problem is when I press the 1st pushbutton it detects that pushbutton and run motor CW or CCW, That means it cannot detect the press of another pushbutton to make it counterclockwise.

I realize that the program isn't detecting the second push button after pressing 1st one. Tried different options to make it work. but failed.

any suggestions?

Here's my code for reference:-

#include <AccelStepper.h>

const int button1Pin = A2 ;
const int button2Pin = A1;

int button1State = 0;
int button2State = 0;

boolean flag1 = 0;
boolean flag2 = 0;

AccelStepper stepper = AccelStepper(1, 8, 9);
void setup()
{  
   pinMode(button1Pin, INPUT);
   pinMode(button2Pin, INPUT);  
   
   Serial.begin(9600);
}

void loop()
{  

      int sensorReading = analogRead(A0);
      int motorSpeed = map(sensorReading, 0, 1023, 500, 1000);
      button1State = digitalRead(button1Pin);
      button2State = digitalRead(button2Pin);

     stepper.setMaxSpeed(2000);
     stepper.setSpeed(motorSpeed);
     
     if (button1State == HIGH)
       {
       
        stepper.setSpeed(motorSpeed);
        Serial.print("ok");
        stepper.runSpeed();
       

       }
 
  if (button2State == HIGH)
       {

        Serial.print("ok2");
        stepper.setSpeed(-motorSpeed);
        stepper.runSpeed();

      }
}

Another problem is in this current code, it cannot detect the potentiometer input inside the if ( button state ) {} loop.

it would be a great help pointing out my mistakes.
