Here is how to use your Raspberry Pi's GPIO pins... Part 2... Make sure to watch Part 1 first:

youtube.com/watch?v=H08BLCuhaxg

Commands used:

sudo apt-get install python-rpi.gpio

And if needed:

sudo apt-get install python-dev

Code is as follows:

import RPi.GPIO as gpio
import time

#set up pin 14 as an output
gpio.setmode(gpio.BCM)
gpio.setup(14, gpio.OUT)

#Make an LED flash on and off forever
while True:
gpio.output(14, gpio.HIGH)
time.sleep(1)
gpio.output(14, gpio.LOW)
time.sleep(1)

INDENTATION IS WRONG... Everything in the while loop MUST be 4 spaces in or 1 tab....

Happy Piing!
