WS2812 and NeoPixel LEDs open up endless creative lighting possibilities. From slow fades to pulsing rainbows and strobe patterns, programmable LED strips can bring visual projects to life. Designing patterns manually in code, however, can be slow and time consuming.
This WS2812 Pattern Editor lets you visually design LED animations and export them for your microcontroller project. Select colours, timing, brightness and pattern flow, then preview the animation directly in the browser before sending it to your LEDs.
WS2812 Pattern Editor
This tool is ideal for hobby projects, music reactive lighting, holiday displays, PC case mods and smart room lighting. By adjusting animation steps visually, you avoid guesswork and get exactly the pattern you want. The editor supports smooth gradients, repeating segments and single frame colour placement for fine control.
Use this editor for:
- Addressable LED strips and rings
- Arduino and ESP32 LED projects
- PC and desk RGB lighting setups
- Christmas or holiday lighting sequences
- Visual prototyping before writing code
You can export generated pattern data into common formats ready for FastLED, WLED or custom firmware. If you later want code export blocks for Arduino or ESP32, tell me and I can generate a copy paste ready format.
