Raspberry Pi Digital Signage with Pi Presents

Intro

You can use a Raspberry Pi attached to a monitor or TV as a affordable digital signage solution to display websites, images or videos. In this example, we use Pi Presents to create a multimedia digital signage solution.

This can be used to create touchscreen systems, button controlled kiosk displays, repeating multimedia shows, audio-visual interpretation of exhibits and lots more.

What you need

How

First, make sure your Raspberry Pi is up-to-date and install the required software. Pi Presents requires the Python Imaging Library (PIL), MPlayer, Uzbl webkit browser and the X server utilties package.

We will also install unclutter to stop the mouse cursor from getting in the way on our displays.

sudo apt-get update
sudo apt-get install python-imaging
sudo apt-get install python-imaging-tk
sudo apt-get install x11-xserver-utils
sudo apt-get install unclutter
sudo apt-get install mplayer
sudo apt-get install uzbl

We also need to install pexpect, which is a ‘Python module for controlling interactive programs in a pseudo-terminal’.

 wget http://pexpect.sourceforge.net/pexpect-2.3.tar.gz
 tar xzf pexpect-2.3.tar.gz
 cd pexpect-2.3
 sudo python ./setup.py install

Next, we can download and extract PiPresents-Next.

This needs to be down from the Raspberry Pi desktop interface (either Pixel or startx). Open the terminal application and then run:

 wget https://github.com/KenT2/pipresents-next/tarball/master -O - | tar xz

You should now have a new directory available with the version number. You can rename it to pipresents to make it easier to access. e.g.

mv KenT2-pipresents-next-aa66e61 pipresents

Then navigate into your pipresents folder and run the python file:

  cd pipresents
  python pipresents.py

Ok, so now it’s installed, we need to create some profiles to use.

There’s an example profile you can download that includes a multimedia slideshow with music, text and graphics. It’s a good basis to use for your own profile, particularly when you’re just getting started.

There are also many profile exameples and exenstive documentaiton available in the manual (PDF)
