John Park’s Ninja Timer Demo @adafruit #adafruit @johnedgarpark

Build a huge timer for an event or race. It’s a digital segment display made from RGB NeoPixels!
Laser-cut acrylic is layered to create large, sharp, segments that are backlit by NeoPixel strips, and controlled with an Arduino. Huge buttons for start and stop are wired in over CAT5 network cable
