Additional

If you working on Ubuntu Server rather then the Raspbian you may want to give your user rights to interact with GPIO interface.

For doing that you need:

• Create gpio group
• Give a gpio group full rights to GPIO interface
• Add your user to the gpio group

Create a GPIO group

Just type in a command line interface and press enter

sudo addgroup gpio

Give the gpio group full rights to the GPIO interface

Add a line below to the file /etc/udev/rules.d/10-raspi.rules you have to create as well.

SUBSYSTEM=="input", GROUP="input", MODE="0660"
SUBSYSTEM=="i2c-dev", GROUP="i2c", MODE="0660"
SUBSYSTEM=="spidev", GROUP="spi", MODE="0660"
SUBSYSTEM=="bcm2835-gpiomem", GROUP="gpio", MODE="0660"

SUBSYSTEM=="gpio", GROUP="gpio", MODE="0660"
SUBSYSTEM=="gpio*", PROGRAM="/bin/sh -c '\
        chown -R root:gpio /sys/class/gpio && chmod -R 770 /sys/class/gpio;\
        chown -R root:gpio /sys/devices/virtual/gpio && chmod -R 770 /sys/devices/virtual/gpio;\
        chown -R root:gpio /sys$devpath && chmod -R 770 /sys$devpath\
'"

This changes an owner group to gpio on some system objects related to gpio device. Also it gives full rights to the gpio group members.

Add your user to the gpio group

sudo usermod -aG gpio username
