Unicorn HAT (HD) simulator - Originally by Jannis Hermanns <>

Project description

Simulates an Unicorn HAT HD (and should work for the 8x8 HAT and the 8x4 PHAT as well) using pygame.


If you want your code to run on your computer as well as your Pi, you could do something like this:

  1. pip install unicorn-hat-sim (or pip2 or pip3 depending on your setup)

  2. Adjust your import unicornhathd statement as follows:

    import unicornhathd as unicorn
    print("unicorn hat hd detected")
except ImportError:
    from unicorn_hat_sim import unicornhathd as unicorn

You can choose from import unicornhathd (16x16), import unicornhat (8x8) and import unicornphat (8x4).


(Note that this gif has a low framerate, the simulator runs nice and smooth in real life)




  • [ ] find a python person who shows me how this would be done properly

  • [ ] fix/check rotation

  • [ ] add a proper LED glow effect so it looks more like a real unicorn HAT

  • [ ] publish via pip
