21st Century Learning and Teaching

I made an LED mask with 11 patterns to demonstrate how to code for a matrix that is not rectangular. It runs on an Arduino Nano and uses FastLED library. If you just want to look at pretty flashing lights, skip to 07:35. Watch right to the end to see the basic sound reactive part - this still needs some work!

Xmas Star with NeoPixels WS2812B made from cardboard Soon there will be Christmas and decorations are getting put around the house worldwide as it is tradition since ages to do so. That's also the time for tinkerers, makers to GET some new ideas. Well, I thought on a project which everybody could do…
