Arcade Retro Clock 

NEW! Dot Invaders

The Running Man


Arcade Retro Clock started out as a project on an 8x8 matrix. Over the years it has been converted to 16x16 and now 64x32. Each conversion process involved solving many bugs and enhancing the game play especially with respects to the computer's ability to play against itself.

For LEDarcade, I decided to isolate classes, functions, sprites, etc. that are used specifically for displaying messages and animations and to exclude any functions used to control the specific games.

What it can do

LEDArcade has many classes, functions, pre-defined sprites that are used to do the following:

  • draw a sprite
  • move a sprite
  • make a sprite float across the screen
  • raw animated sprites floating across the screen
  • draw text of multiple sizes
  • scroll text left or right at various speeds
  • multiple ways to clear the screen (zooming in / zooming out / fading)
  • scroll the screen around a large map, displaying only a section of the map in a window

There are many more functions available but they are fairly complex. As this project moves forward I will create more examples and document each function.

Example title screens






Modify the test.py script to contain the messages you want to display. Then execute by issuing the command:

 sudo python3 test.py

I blog about my Raspberry Pi projects.

## Retro Arcade Games
I have programmed 9 games on several sizes of LED matrixes using this library (in various forms). As I convert the games to this final library I'll add them here.

# Dot Invaders
Dot Invaders is my take on the classic arcade game Space Invaders.

sudo python3 DotInvaders.py



This project has been in development for 5 years. I have been gathering all my code and functions and putting them into a library.

I have been programming computers for 40 years. Basic, C, Pascal, Cobol, SQL. Python is by far my favorite language, followed by SQL.
