“In this guide, we will cover how you can create the hardware and software for an Arduino LED rave mask. Feel free to refer to the GitHub repository for this Arduino project.
The mask itself consists of 7 rows of WS2182B 144 LEDs/m NeoPixels. There are a total of 161 LEDs, with the first row being 26. Each row decrements by 1, which means the 7th row will have 19 NeoPixels. Since we are decrementing by an odd number, we will line up the pixels to be in-between the two pixels above it. This results in a hexagon-like geometric pattern which will allow us to make awesome patterns for our visuals.”
