I just finished putting this little project together using the tutorial provided by Adafruit. I'm very happy everything worked with the code since I'm not very experienced with coding.
But now that I have it running I would like to add or change one or all of the patterns in the code but I'm not familiar with this level of coding. Below is the full project code with a link to the tutorial.
If someone can help or explain how to add more pattern modes that would be appreciated. I know that with trinket memory is an issue so thats why am asking for some assistance with this.

This is the full project code with 2 programed modes. I would like to replace the modes but I cant identify what needs to be chance
