Dot Matrix

Install

Or by hand, in a Next.js project with shadcn set up. It writes components/pastetaste/dot-matrix.tsx.

Install the pastetaste component "Dot Matrix" (dot-matrix) into this Next.js project and use it.

What it is: Numbers and short labels on a 5×7 dot grid, like a payment terminal. Static text, or counting up to a value the first time it scrolls into view.

Before you place it, ask me (one short message, in my language; "skip" = sensible default): which page and section it goes in, my brand colour (hex), the text, labels or images it should show, and whether I want my logo or my own copy in the demo content. Then:

Steps:
1. If the project has no components.json, run: npx shadcn@latest init -y -d. Then run: npx shadcn@latest add https://pastetaste.com/r/dot-matrix.json
   (it writes components/pastetaste/dot-matrix.tsx; install any npm packages it reports).
2. Import it: import { DotMatrix } from "@/components/pastetaste/dot-matrix" (check the file for the exact named export).
3. Put it where it fits on the page I name, keep the rest of the page untouched, and pass props for my colours instead of editing the installed file.
4. It does not depend on Tailwind; colours come from CSS variables (--pt-*) or props.
5. It supports prefers-reduced-motion with a still state; do not remove it.

Props (all optional unless the type has no default):
- text: string — Static text; ignored when value is set.
- value: number — Number to count up to on first view.
- format: (n: number) => string = toLocaleString('en-US') — Formats the counted number, e.g. a currency prefix.
- duration: number = 1.6 — Count duration in seconds.
- dot: number = 4 — Dot diameter in px.
- gap: number = 2 — Space between dots in px.
- color: string = currentColor — Lit dot colour.
- ghost: number = 0.1 — Opacity of unlit dots; 0 hides them.
- tracking: number = 0 — Extra blank dot columns between characters; 1 gives display-board spacing and reads better at headline sizes.
- shape: 'circle' | 'square' = 'circle' — Dot shape.
