LED Firework for T-shirt
thingiverse
I have designed a plate for New Year's Eve that can be inserted with WS2812b LEDs. It is controlled by an Arduino Nano to simulate fireworks. The entire setup is powered by a 9V block battery and is bright enough to shine through a thin T-shirt. The source code for the Arduino has been uploaded (platform.io project). I used pin 14 for the small fireworks and pin 16 for the large ones. ### BOM: + 63x WS2812b LEDs + 1x Arduino Nano + 2x 220 Ohm resistors + 1x 9V block battery + 1x Battery clip + 4x M3 screws and nuts + Wire and soldering tin. ### Videos: https://youtu.be/Ld_yu6DL8ls https://youtu.be/NEfYGXMbfnU
