Getting it rolling

OK, that's a lot of theory, so now let's fire up one of our motors via Raspberry Pi. To do that, go ahead and connect the motor and the motor driver as shown:

Now, once you are done with it, let's upload the code and see what happens:

import RPi.GPIO as GPIOfrom time import sleepGPIO.setmode(GPIO.BCM)Motor1R = 20Motor1L = 21GPIO.setup(Motor1R,GPIO.OUT)GPIO.setup(Motor1L,GPIO.OUT)GPIO.output(Motor1R,GPIO.HIGH)GPIO.output(Motor1L,GPIO.LOW)sleep(5)GPIO.output(Motor1R,GPIO.LOW)GPIO.output(Motor1L,GPIO.HIGH)sleep(5)GPIO.cleanup()

Now, let's understand the code a bit:

Motor1R = 20Motor1L = 21

Pin number 20 is connected to IN 1 ...
