ChromaBay

ESP32 LEDs with Bluetooth

Free · Designed for iPad. Not verified for macOS.

Turn LED strips into a canvas: build animated light patterns in a visual node editor, tweak them live, and beam them to your ESP32 over Bluetooth. ChromaBay turns addressable LED strips into a canvas. Build glowing, animated light with a visual node editor — no code. Chain generators and effects, dial in the look, and watch it render live before it ever reaches your lights. DESIGN • A node-based editor: start from generators (rainbow, plasma, noise, radial, moving blobs, raindrops, fire, gradients, interference, orbiting color "Venn", moving color bands, and a Wave), then stack modifiers (blur, sharpen/edge/emboss convolutions, blend, fade, glitch, hue-rotate, mirror, tile, scroll, posterize, invert, and video-style feedback for trails and tunnels). • Fill any SVG shape and spin, pulse, or drift it. • Automate any control with an LFO, noise, or random — turn a static value into living motion. PERFORM • An Interact screen with big knobs and a color wheel to play your lights live. • Make an automation's speed or range interactive, so you can jam in real time. CONTROL YOUR HARDWARE • Connect over Bluetooth to ESP32-based controllers driving addressable LEDs (WS2812/NeoPixel and friends). • Set brightness and push patterns instantly. • Sync a playlist that auto-cycles patterns in lockstep across multiple devices. • Update device firmware over the air. SHARE • Keep a personal pattern library that syncs to your account. • Share any pattern with a single link — the whole pattern travels in the URL. • Browse a community gallery and adopt others' patterns. You can explore the entire editor and live preview without any hardware — connect a device when you're ready to light up the room.
