Install RPi.GPIO Library In Raspbian

The RPi.GPIO Python library allows you to easily configure and read-write the input/output pins on the Pi’s GPIO header within a Python script. In order to use it you need to install the package as this isn’t usually included in SD card images.

First of all Install Python Development Software.
Python development software is worth installing as there are many examples on the internet using this language for the Raspberry Pi

Enter the following at the command line
Follow the prompts to download and install the python package

sudo apt-get install python-dev

Step 1 – Download the library


Step 2 – Install the library

sudo dpkg -i python-rpi.gpio_0.3.1a-1_armhf.deb

Example Usage
Copy the following script into a text file called “” :

import RPi.GPIO as GPIO

# to use Raspberry Pi board pin numbers

# set up the GPIO channels - one input and one output
GPIO.setup(11, GPIO.IN)
GPIO.setup(12, GPIO.OUT)

# input from pin 11
input_value = GPIO.input(11)

# output to pin 12
GPIO.output(12, GPIO.HIGH)

# the same script as above but using BCM GPIO 00..nn numbers
GPIO.setup(17, GPIO.IN)
GPIO.setup(18, GPIO.OUT)
input_value = GPIO.input(17)
GPIO.output(18, GPIO.HIGH)

To run this script you can use the following command :

sudo python

You need to include “sudo” in front of this command as the GPIO library requires root privileges.
