GPIO experiments on the Raspberry Pi

• One of RPi.GPIO, or

sudo pip install RPi.GPIO

• wiringPi

git clone git://git.drogon.net/wiringPi cd wiringPi sudo ./build

Then, the Python wrapper library, WiringPi-Python

sudo pip install wiringpi

Or, buid it from source:

git clone https://github.com/WiringPi/WiringPi-Python.git cd WiringPi-Python sudo git submodule update --init sudo python setup.py install

NOTE: wiringPi accesses the GPIO pins differently than RPi.GPIO, therefore, you can access the GPIO pins without root access with wiringPi.

e.g. sudo -u /usr/local/bin/gpio export out
