Here is a simple project that only needs a raspberry pi, pi face, python, jumper wires, and a stepper motor-that's it!
Step 6:
Sixth type this into a python file (or copy-paste):

from time import sleep
import piface.pfio as pfio
pfio.init()
print"Type: direction(rotations, speed)"
def anticlockwise(rotations, speed):
sleep_time=0.1 / float(speed)
for loop in range(1,int(512*float(rotations))):
pfio.digital_write(4,1)
sleep(sleep_time)
pfio.digital_write(7,0)
sleep(sleep_time)
pfio.digital_write(5,1)
sleep(sleep_time)
pfio.digital_write(4,0)
sleep(sleep_time)
pfio.digital_write(6,1)
sleep(sleep_time)
pfio.digital_write(5,0)
sleep(sleep_time);
pfio.digital_write(7,1);
sleep(sleep_time)
pfio.digital_write(6,0)
sleep(sleep_time)
pfio.digital_write(7,0)
def clockwise(rotations, speed)
sleep_time=0.1 / float(speed)
for loop in range(1,int(512*float(rotations)))
pfio.digital_write(7,1)
sleep(sleep_time)
pfio.digital_write(4,0)
sleep(sleep_time)
pfio.digital_write(6,1)
sleep(sleep_time)
pfio.digital_write(7,0)
sleep(sleep_time)
pfio.digital_write(5,1)
sleep(sleep_time)
pfio.digital_write(6,0)
sleep(sleep_time)
pfio.digital_write(4,1)
sleep(sleep_time)
pfio.digital_write(5,0)
sleep(sleep_time)
pfio.digital_write(4,0)
Step 7:
Done!
The motor I used was 28BYJ48 5V DC
Your motor should now obey orders you type!
(make your speed 10-600)
If you have any problems, ask me!
