Great project

[jbreizh]

I had also done project on lightpainting 2 years ago https://github.com/jbreizh/ImagePainting and i was upgrading/testing it for the new software version when i find your project. Great projet !! i am especialy impress with the hardware and all the build in arduino code. When you chose to build a full feature stick, i choose to build a smartphone driven stick (way simpler especialy for the hardware and arduino code). Anyway, maybe you can salvage some idea from my project although the code quality is not the best as i am just a french maths teacher...
