Schematics

Schematic of this specific Motor Driver from Open-Electronics.org

This is a nice driver...

Code

Motor Geaux, Motor Backwards, and Motor Stop...

Python
This makes one, single motor go forward, go backwards, and stops. Then, the software ends and the motor stops.
import Adafruit_BBIO.GPIO as GPIO
import time

Master_Pin =  "P9_21"
ln1 =         "P9_22"
ln2 =         "P9_12"

if __name__=="__main__":

    GPIO.setup(Master_Pin, GPIO.OUT)
    GPIO.output(Master_Pin, GPIO.LOW)

    GPIO.setup(ln1, GPIO.OUT)
    GPIO.setup(ln2, GPIO.OUT)

    GPIO.output(Master_Pin, GPIO.HIGH)
    GPIO.output(ln1, GPIO.HIGH)
    GPIO.output(ln2, GPIO.LOW)
    time.sleep(5)

    GPIO.output(Master_Pin, GPIO.HIGH)
    GPIO.output(ln1, GPIO.LOW)
    GPIO.output(ln2, GPIO.HIGH)
    time.sleep(5)
    print "I love your body Larry!"

    GPIO.output(Master_Pin, GPIO.LOW)

    GPIO.output(Master_Pin, GPIO.LOW)
    GPIO.cleanup()

RE: On flack, Making Two Motors Go and Do Stuff...

Python
This is the software to make two motors move around some. I hope to make things more accessible for other people soon. Enjoy...

    print ("I love your body Larry!")
    time.sleep(8)

    GPIO.output(ln1b, GPIO.LOW)
    GPIO.output(ln2a, GPIO.LOW)
    GPIO.output(ln2b, GPIO.LOW)
    print ("Waka, Waka, Waka!")
    time.sleep(8)

    GPIO.output(Master_Pin1, GPIO.LOW)
    GPIO.output(Master_Pin2, GPIO.LOW)

    GPIO.cleanup()

Many Moons!

Just some ideas on getting up and running w/ the L298 and a motor driver from Open-Electronics.org.
