Preview notes

Loading example…

Configure one to five physical strips above; their LED indices form one continuous WLED address range. Line direction can alternate the flow within each strip; a new strip starts left to right. Line gap controls wrapped lines, and Strip gap adds spacing at strip boundaries. These are browser approximations of WLED effect motion. Built-in WLED 16 palettes are included; exact random timing, hardware color order and custom palettes can differ. Exposure brightens the whole preview. Gamma lift makes dim LED dots more visible, even at very low preset brightness, while glow stays tied to the selected brightness. Brightness overrides affect this preview only. Effect speed adjusts motion without changing playlist durations; 1× follows the WLED speed setting, with effect-specific approximations.

Version history · 0.1.1–v0.1.30

v0.1.30

Centered the animated logo and caption, added tap-to-cycle logo speeds 1 → 0 → 3 → 2, refreshed cyan/violet/pink accents within the dark theme, and implemented BPM (FX 68), Plasma (FX 97), and Noise Pal (FX 107).

v0.1.29

Changed the logo caption to WLED 16 preset preview; added Noise 1 (FX 70), Noise 2 (FX 71), Sinelon Rainbow (FX 94), and Ripple Rainbow (FX 99) with WLED-inspired motion and palettes.

v0.1.28

Added the responsive pghWebLED dot-matrix header logo with equal-size LED nodes, circular diode outlines, animated color flow, and a layered diffuser glow.

v0.1.27

Added a line-direction selector to draw each strip in the same direction or snake alternate lines, including right-aligned partial reverse lines while keeping continuous WLED LED indices.

v0.1.26

Renamed the project pghWebLED; added 1–5 physical strips with shared or individual LED lengths, separate line and strip spacing controls, and continuous WLED index mapping across wrapped strips.

v0.1.25

Combined the complete presets file and selected preset JSON editors into one tabbed panel; preserved selected preset syncing, imports, draft edits, and mobile layout.

v0.1.24

Added Dissolve Rnd (FX 19), Chase Flash (FX 31), Chase Flash Rnd (FX 32), Sine (FX 108), and PS Hourglass (FX 207) with effect timing, colors, and particle motion.

v0.1.23

Set exposure and gamma lift defaults to 1; scaled ordinary 80-LED lines to fit portrait phones while retaining horizontal scroll for wide LED-gap layouts.

v0.1.22

Corrected Pacifica (FX 101) wave phase timing: FastLED beat16 values 301–601 are Q8.8 fractional BPM; previews now move at WLED’s intended speed.

v0.1.21

Added Fairytwinkle (FX 51), Fire 2012 (FX 66), Twinklefox (FX 80), Twinklecat (FX 81), and Candle (FX 88), including effect timers, palette colors, and moving flicker.

v0.1.20

Added visible version numbers and the full version history to the preview and standalone HTML; established the 0.1.x release sequence.

v0.1.19

Added Pride 2015 (FX 63), aligned Pacifica’s palette motion with WLED’s effect-frame timing, and added a persistent list of unsupported FX IDs.

v0.1.18

Added Aurora (FX 38) and Pacifica (FX 101) wave previews; set the default to 80 LEDs per line.

v0.1.17

Added an editable JSON box for the selected preset, live preview updates, and synchronization with the full export while preserving other presets and metadata.

v0.1.16

Added round or square LEDs and a 0–5× LED-width gap control; widened and scrolled strips when larger gaps need more room.

v0.1.15

Rebuilt Juggle (FX 64) with frame-to-frame fading trails and set Ignore preset brightness to checked by default.

v0.1.14

Replaced per-LED SVG circles and blur filters with Canvas drawing; added separate FX and drawing time measurements.

v0.1.13

Added independent overrides for overall preset and segment brightness; raised the default gamma lift so dim Patriot stripes remain visible.

v0.1.12

Added eight 1D PS particle effects (202, 204–206, 208, 210, 211, 213) and the WLED 1D Solid fallback for 2D PS effects.

v0.1.11

Added 20 more 1D FX approximations, including Breathe, Random Wipe, Sweep, and Chase 2.

v0.1.10

Corrected Chunchun (FX 111) so its secondary color stays in the background while birds move over it.

v0.1.9

Fixed Copy Segment’s FullStack mode to copy physical LEDs after source grouping and spacing.

v0.1.8

Added Lightning, Halloween Eyes, Drip, Multi Candle, and related FX; clarified Copy Segment length limits and 2D fallbacks.

v0.1.7

Added Noise 3 (FX 72) with moving three-dimensional noise and WLED palette sampling.

v0.1.6

Corrected Copy Segment to use matching logical LED positions instead of stretching a shorter source; expanded the gamma lift range.

v0.1.5

Added the effect-speed control and refined Juggle timing for WLED’s Q8.8 beat values.

v0.1.4

Added the gamma lift slider to make very dim LED colors visible while keeping glow tied to brightness.

v0.1.3

Expanded effect support with Fireworks Starburst (FX 89) and others; added built-in palettes, playlists, and individually colored LEDs.

v0.1.2

Added a configurable number of LEDs per line for a wrapped strip layout.

v0.1.1

Created the SVG browser preview with JSON import, preset selection, segment rendering, Copy Segment, and the initial 26 FX.
