Please show your code and error code so we can tell which stepper library you are trying to use.

Your error was probably...

```arduino
Stepper.h not found in library

```

To resolve this, use your IDE to find TOOLS \>\> INCLUDE LIBRARIES \>\> MANAGE LIBRARIES then enter Stepper... you will see Stepper by Arduino... click "install" and when it is complete, try compiling your sketch again.

You didn't posted your sketch as a

## code-section

It is seen as a very bad habit on this forum to post screenshots.

Seems you want to play a snapchat short messages ping-pong game of  
posting a single sentence waiting for a single-sentence answer.

Sure if you like this way. Making your code run will take weeks.

I'm pretty sure that you agree and will follow the way how to solve your problem mimimum 200 minutes **faster**.  
This requires to **invest** 20 minutes of your precious time to read how to speedup solving your problems.

Directly after registering you got presented informations how to speed up solving your problem.  
You should really read it.

I'll be very Direct and say I Struggle With my Traumatic Brain injury from an accident and cant route my learning to learn as I used to.. it won't seam like it with the way I write, I do rely on people a lot, please dont bother to accuse me of "trying to play "snap-chat ping pong games games" and if that seams to bother you, I have no apology for you, as that is a you problem not a me problem. but if you're wiling to understand then we are on mutual ground, on which I'm thankful. I will Try my best to learn the link which you have attached but as I very slowly do so I will very much so probaly continue(at my best minimum) continue to over ask this way, I don't know weather to apologise for that or not?

Not.

Pro-tip: If you are tired of hearing from someone, (1) in the upper-right of the page (2) mouse-click your avatar (3) click "profile" (4) click "preferences" (5) click "users"... you will see (6) ignore and (7) mute. You can "un-see" anyone you choose by selecting their username.

Check answer #8 and the syntax of the line that the compiler highlighed in the screenshot you posted.

What do you expect that line to do?

My eyes suck and I can barely read the code and error in your post #8.

If, instead of a screenshot of the code, you cut and pasted the actual code and error message, it would help folks help you.

If I squint hard, it looks like this line is ill formed:

 ![image](https://europe1.discourse-cdn.com/arduino/original/4X/e/7/c/e7c8d6584a30b569c793b4dadf7ff9bbc2206beb.png)

It looks like `myStepper.setSpeed(motorSpeed 20);` is confusing things. I'd try either

```arduino
myStepper.setSpeed(motorSpeed);`

```

or

```arduino
myStepper.setSpeed(20);`

```

depending on what you are trying to accomplish.

Do you have an `#include <stepper.h>` line in there somewhere? Try proven code from the  
examples in File/Examples/Stepper/

Very important information to understand your situation.  
I am sorry if my former post offended you.

So shall your code be a simple test if the stepper-motor runs?

If you follow this click-path  
file - examples - stepper - one revolution

 ![image](https://europe1.discourse-cdn.com/arduino/original/4X/f/2/0/f2005a496c80cc4adc5d53c0146111b206ac3cff.png)

you will find this demo-code

```arduino

/*
 Stepper Motor Control - one revolution

 This program drives a unipolar or bipolar stepper motor.
 The motor is attached to digital pins 8 - 11 of the Arduino.

 The motor should revolve one revolution in one direction, then
 one revolution in the other direction.

 Created 11 Mar. 2007
 Modified 30 Nov. 2009
 by Tom Igoe

 */

#include <Stepper.h>

const int stepsPerRevolution = 200; // change this to fit the number of steps per revolution
// for your motor

// initialize the stepper library on pins 8 through 11:
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);

void setup() {
  // set the speed at 60 rpm:
  myStepper.setSpeed(60);
  // initialize the serial port:
  Serial.begin(9600);
}

void loop() {
  // step one revolution in one direction:
  Serial.println("clockwise");
  myStepper.step(stepsPerRevolution);
  delay(500);

  // step one revolution in the other direction:
  Serial.println("counterclockwise");
  myStepper.step(-stepsPerRevolution);
  delay(500);
}

```

to make your stepper-motor rotate.

Did you do compile and upload some other basic codes?  
Like blinking the onboard LED?
