Having a problem with the code to get this working?
ERRORS EVERYWHERE
2X MotorKnob and 1X Stepper Motor Control - speed control
stepper 1
digi pin 0-3
ana pin 0 - potentiometer
stepper 2
digi pin 4-7
ana pin 1 - potentiometer
stepper 3
digi pin 8-11
ana pin 2 - potentiometer
Any help would be much appreciated
thanks kieren
You seem to have forgotten to post your code
Not only did you forget to post your code but you also forgot to give a link to the datasheet for the stepper motors you are using and a link to the stepper motor drivers you are using.
And you need to provide a diagram showing how everything is connected - especially the power supplies (note the plural).

I don't know where to start coding I made an attempt but it didn't seem to work and online videos aren't exactly helping, I posted this form because I'd wanted to know how to get this working, can you help
thanks

Post whatever code you have - it will provide a basis for further advice. At the moment you have given us nothing to work with.
There are lots of Threads on the forum about those stepper motors and drivers. Use Google to find them.

all I want to find out is how to change the pins on MotorKnob code
/*
* MotorKnob
*
* A stepper motor follows the turns of a potentiometer
* (or other sensor) on analog input 0.
*
* http://www.arduino.cc/en/Reference/Stepper
* This example code is in the public domain.
*/
#include <Stepper.h>
// change this to the number of steps on your motor
#define STEPS 100
// create an instance of the stepper class, specifying
// the number of steps of the motor and the pins it's
// attached to
Stepper stepper(STEPS, 8, 9, 10, 11);
// the previous reading from the analog input
int previous = 0;
void setup()
{
// set the speed of the motor to 30 RPMs
stepper.setSpeed(30);
}
void loop()
{
// get the sensor value
int val = analogRead(0);
// move a number of steps equal to the change in the
// sensor reading
stepper.step(val - previous);
// remember the previous value of the sensor
previous = val;
}
and Stepper Motor Control - speed control
/*
Stepper Motor Control - speed control
This program drives a unipolar or bipolar stepper motor.
The motor is attached to digital pins 8 - 11 of the Arduino.
A potentiometer is connected to analog input 0.
The motor will rotate in a clockwise direction. The higher the potentiometer value,
the faster the motor speed. Because setSpeed() sets the delay between steps,
you may notice the motor is less responsive to changes in the sensor value at
low speeds.

#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);
int stepCount = 0; // number of steps the motor has taken
void setup() {
// nothing to do inside the setup
}
void loop() {
// read the sensor value:
int sensorReading = analogRead(A0);
// map it to a range from 0 to 100:
int motorSpeed = map(sensorReading, 0, 1023, 0, 100);
// set the motor speed:
if (motorSpeed > 0) {
myStepper.setSpeed(motorSpeed);
// step 1/100 of a revolution:
myStepper.step(stepsPerRevolution/100);
}

Read How to Use the Forum and post your code with code tags so it looks like this Use the button like the image below.
You have two completely separate program in your Post and I only found that out after I loaded the code into my text editor.
As far as I can see you have not made any changes to those two programs. Earlier you said
I made an attempt but it didn't seem to work
. Post that code and then we can see the difficulties that you see and can give some practical advice.

the
I made an attempt but it didn't seem to work
was every time i changed any pin numbers it errored?
changes made?

I can't help when you only give inadequate information like this.
I don't understand how you think that I could.
