[Solved]How to make my stepper motor run clockwise and counterclockwise? I'm relatively new to Arduino thus need your help to figure out why my stepper motor doesn't rotate clockwise and counterclockwise. All I could do was to make it rotate only in one direction.

I am using AccelStepper Library

Here is my code:


#include &lt;AccelStepper.h&gt;
//Define stepper motor connections
#define dirPin 4
#define stepPin 14
//Create stepper object
AccelStepper stepper(1,stepPin,dirPin); //motor interface type must be set to 1 when using a driver.
void setup()
{
  stepper.setMaxSpeed(1200); //maximum steps per second
}
void loop()
{
  stepper.setSpeed(1200); //steps per second
  stepper.runSpeed(); //step the motor with constant speed as set by setSpeed()
}


I have tried to add delay and counterclockwise code but its not working.

#include &lt;AccelStepper.h&gt;
//Define stepper motor connections
#define dirPin 4
#define stepPin 14
//Create stepper object
AccelStepper stepper(1,stepPin,dirPin); //motor interface type must be set to 1 when using a driver.
void setup()
{
  stepper.setMaxSpeed(1200); //maximum steps per second
}
void loop()
{
  Serial.println("clockwise");
  stepper.setSpeed(1200); //steps per second
  stepper.runSpeed(); //step the motor with constant speed as set by setSpeed()
  delay(1000);
  Serial.println("counterclockwise");
  stepper.setSpeed(-1200); //steps per second
  stepper.runSpeed(); //step the motor with constant speed as set by setSpeed()
  delay(1000);
}
Hi here it the reference to the library functions that are available in accelstepper library.

Go through the link, it will provide you the issues with your code and example for your application like @smajli said steps more than 1000 is unreliabe, here you can see setSpeed(float) function where setting negative or positive sign selects the direction and value set the speed of rotation.
