Oct 25, 2023 · Connect the positive of the LEDs to a suitable power supply and connect the Arduino to its own power supply. Lots of tutorials for wiring "neo pixels" will show you how.

Oct 13, 2015 · Based on a great suggestion by Cindy W, we've started this topic for folks to post their LED lightning effects.

Nov 9, 2015 · In this article I'll show you a several LED strip effects for NeoPixel and FastLED. The code works for both libraries and any strip they support (theoretically).

Sep 17, 2021 · I have a ceiling covered in WS2811, a total of 6 different strands so I don’t want them all to flash, but rather lightning “strikes” to hit different parts of the ceiling at different times. Can anyone point me to a code they’ve seen that does this? Or do I need to program this? It’d be great to find a drag and drop code!

Oct 2, 2020 · In short (for a Halloween prop), I'm trying to create a small string of lights that I can run a preset program on (likely a variation on the Fire effect in fastled, but hopefully much slower and with random start points).

Nov 14, 2022 · I found this tutorial on getting that going https://create.arduino.cc/projecthub/john_dillenburg/arduino-nano-33-iot-12v-ws2811-led-strip-controller-c04f7a and did some research on wiring this up.

FastLED is a fast, efficient, easy-to-use Arduino library for programming addressable LED strips and pixels such as WS2810, WS2811, LPD8806, Neopixel and more. FastLED is used by thousands of developers, in countless art and hobby projects, and …

This project uses the Arduino Nano 33 IoT, the Arduino IoT Cloud, and optionally streaming ACN or Alexa to control 12 volt WS2811 LEDs. There are 4 connectors for 4 LED strips and each strip can chain together hundreds of LEDs.

Inside the WS2812 and WS2812B packages resides an embedded version of the WS2811 constant-current LED driver, as well as 3 individually controlled LEDs; one red, one green, and one blue. In a compact package, the WS2811 includes: - An internal oscillator - A signal reshaping and amplification circuit - A data latch

Jun 16, 2017 · A 12volt WS2811 strip uses one driver chip per three LEDs, so you can't control each LED individually. OP can't have used the blown Nano properly, because the pins never have been soldered.
