I worked on trying to code the stepper motor:

#!/usr/bin/python

# Import required libraries

import sys

import time

import RPi.GPIO as GPIO

 

# Use BCM GPIO references

# instead of physical pin numbers

GPIO.setmode(GPIO.BCM)

 

# Define GPIO signals to use

# Physical pins 11,15,16,18

# GPIO17,GPIO22,GPIO23,GPIO24

StepPins = [17,22,23,24]

 

# Set all pins as output

for pin in StepPins:

  print ("Setup pins")

  GPIO.setup(pin,GPIO.OUT)

  GPIO.output(pin, False)

 

# Define advanced sequence

# as shown in manufacturers datasheet

Seq = [[1,0,0,1],

       [1,0,0,0],

       [1,1,0,0],

       [0,1,0,0],

       [0,1,1,0],

       [0,0,1,0],

       [0,0,1,1],

       [0,0,0,1]]

        

StepCount = len(Seq)

StepDir = 1 # Set to 1 or 2 for clockwise

            # Set to -1 or -2 for anti-clockwise

 

# Read wait time from command line

if len(sys.argv)>1:

  WaitTime = int(sys.argv[1])/float(1000)

else:

  WaitTime = 10/float(1000)

 

# Initialise variables

StepCounter = 0

 

# Start main loop

while True:

 

  print (StepCounter),

  print (Seq[StepCounter])

 

  for pin in range(0, 4):

    xpin = StepPins[pin]if Seq[StepCounter][pin]!=0:

      print " Enable GPIO %i" %(xpin)

      GPIO.output(xpin, True)

    else:

      GPIO.output(xpin, False)

 

  StepCounter += StepDir

 

  # If we reach the end of the sequence

  # start again

  if (StepCounter>=StepCount):

    StepCounter = 0

  if (StepCounter<0):

    StepCounter = StepCount+StepDir

 

  # Wait before moving on

  time.sleep(WaitTime)
