In addition to Michael's excellent reference, it might be worth noting
that the python RPi.GPIO library can use "real" pin numbering rather
than the ridiculous, confusing and potentially damaging BCM numbering
where you need to keep referring to a lookup table.
https://code.google.com/p/raspberry-gpio-python/
There are versions for python 3 and 2, but it should be as easy as:
sudo apt-get update
sudo apt-get install python-dev python-rpi.gpio
and then in your python script
import RPi.GPIO as GPIO
GPIO.setmode(GPIO.BOARD)
GPIO.setup(12, GPIO.OUT, initial=GPIO.HIGH)
And you'll have a HIGH on pin 12. Actual real physical pin 12 that you
can feel along to, not some bizarre alternative you need to lookup on
a table.
It's as easy as that - it can also do edge detection, input detection
and all sorts. Read the docs.
While I'm here, I don't know how accessible is it, but the Adafruit
WebIDE rocks! Anyone tried it?
