This Christmas Tree PCB uses an ATTiny85 to control 8 WS2812B Neopixels with selectable display patterns (which need some work but are functional for now). Push buttons can cycle through the display options as well as enable two PWM outputs intended to draw a Christmas tree on an oscilloscope in XY mode.
