Part 3 of: one button scan to dropbox with your #raspberry pi: buttons

This is just a short one: you'll need to install the gpio stuff so that your python scripts can make use of them:

now if you don't have it already on your pi: install python
    sudo apt-get update
    sudo apt-get install python-dev
    sudo apt-get install python-rpi.gpio
you need the gpio thingy to controll your pi with buttons and let some leds light up

And you'll need some soldering...
I've added 5 LEDs and 5 Buttons and three switches (of which only one is connected to the pi) 
and here's my wiring diagram :D 
You'll need some resistors for the red, green and yellow LEDs and some pullup resistors for the buttons (not sure if they are called pull down resistors in my case as they connect the pins so ground while the button is open...).... pull down.... pull down resistors!
