Pong on a Raspberry PI

2017-12-20 20:43:14
As a self-study project I experimented to create a Pong game + slide shown on a Raspberry PI with Tkinter, GPIO and physical buttons.



Material list

  • Raspberry PI, of course ;-)
  • SD card with Raspbian OS
  • 3 boxes with on/off button like this one
  • Breadboard for the first experimental setup
  • Electrical cable with three wires
  • Some breadboard cables
  • Box to protect the Raspberry PI
  • If you want easy control a bluetooth keyboard and/or Wifi dongle


Assembling

Connect the electric cables to the push buttons.


Optionally, run a first test with a breadboard before assembling in the box.


Integrate the cables in the box.


Connect to the GPIO pins of the Raspberry PI.


Source code

I started with an existing Python pong game from Matt Pugh.

It needed a lot of tweening to make it multiplayer, keep scores and configure it to run smoothly on the PI. It was also extended to have a main page with advertisements and where additional games can be added, you know once, when I have time... ;-)
For the slideshow, I extended the code from Stack exchange.

My complete source can be found here on GitHub.

Some additional Python libaries need to be installed
  • pip install RPi.GPIO
  • pip install keyboard
  • pip install pillow
  • sudo apt-get install python-imaging-tk


Tips & tricks

I tried out many different methods to get rid of the screensaver, but the only good solution turned out to be:
  • sudo apt-get update
  • sudo apt-get install xscreensaver
