Automatic die tester
Some code that repeatedly rolls a die and determines the result using image processing. The result is then logged to a file for postprocessing, e.g. statistical analysis of the die's quality.
To use this, create a template for each of the die sides and place it in the files 1.png, 2.png, etc.
The arduino code is set up to control a stepper motor through a stepstick motor driver, and the image grabbing currently uses gphoto2 to get an image from my DSLR - if your setup is different, you'll have to adapt the code to reflect that.
