On the “original” rule… what does that mean with regards to using code from other open source projects? If I took a graphic display item from a Meggy Jr. RGB project and extended it with new functionality and ported it all to multiple Rainbowduino boards, would that be considered original, or do I need to do all of the graphics code on my own?

We stress original here to avoid 100% same projects, it is recommended to collaborate or work on top of other open source contributions. :slight_smile:
