“n-in-n”, a tradition around ITP, where students complete n project in n day, over a certain number of days.
In this case, 5 days, 5 projects. Besides participating bunch of workshops held by amazing 2nd-years, for my Day1 project, I was thinking about doing StormLighter with this tutorial, but cut it off because of the shortage of materials. So I moved on to other new stuff: Capacity Sensing Library, which I always wanted to try, and RGB Led, because why not. For few hours here’s my rainbow-ish project result.
