This is the software for the “Lichtspiel”, an Arduino-based device I made as a birthday present for my niece. Read more about it here: https://noniq.at/0017/the-lichtspiel/
The project includes a Makefile. If you have Arduino-Makefile installed, you can use the Makefile to build and upload the code, simply adjust the settings in the Makefile accordingly.
Building should work with the standard Arduino IDE, too, but I haven’t tested that.
