A fireworks simulator with NeoPixels, an ESP8266 and Arduino #NeoPixels #Arduino #ESP8266
The Whiskey Tango Hotel blog looks to simulate the lights of fireworks with a single long strip of NeoPixels, aka WS2812B addressable LEDs.
Fireworks are also pretty cool. On the downside they can be dangerous, scare wildlife, start fires, be expensive, illegal, etc. So, until we can afford our own fleet of drones we settled on this alternative.
The hardware is an ESP8266 and a WS2812B LED-strip with 300 LEDs (16.5 feet). We wanted to use a Arduino Nano (because we had one), but due to the amount of memory needed to define the arrays for the 300 LEDs we went with an ESP8266 (because we had one).
See the video below and the post with Arduino source code.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
