# Welcome
Welcome to the Luxio Wiki.
# 1. Buying Hardware
## Controller
For each Luxio LED Strip, you need a single [Wemos LOLIN D1 mini V4](https://www.wemos.cc/en/latest/d1/d1_mini.html). These are only a few dollars on AliExpress.
## LED Strip
Luxio works exclusively with any WS2812b LED Strip.
These are digital, individual-addressable LEDs placed on a strip varying in length — usually between 1 meter and 5 meter.
You can configure the number of LEDs for every Luxio, so you can buy varying lengths. Just keep note of the power usage.
## USB-C Cable
Any USB-C cable that transmits power should work, but keep mind that some have bad quality.

## USB-C Adapter
Any 5V USB-C adapter will work, but it depends on the number of LEDs how much Ampere (A) you need.
The LOLIN D1 mini requires `200 mA`.
As a rule of thumb, every LED requires `50 mA` (that's `0.05 A`) when it's full-brightness and white.
For example, for a 2-meter LED Strip with 120 LEDs, you need `0.2 A + 0.05 ⨉ 120 = 6.2 A`.
As you can see, that's a lot and these adapters are very rare to come by! Regular adapters are only about 2 A. However, in the real world, these adapters perform quite well, because your LED-strip is rarely full-brightness and white — which uses most power.
In our example, a `3 A` adapter would work fine.

# 2. Soldering
Solder the following 3 wires to the LED Strip connector (or to the LED strip directly).
{% hint style="info" %}
The LED strip has a direction, which is shown by arrows. Make sure to solder the `DI` wire on the left side of the arrow.

| LOLIN D1 mini V4 | LED Strip | |
| ---------------- | --------- | -------------------------------------------------- |
| `GND` | `GND` | White |
| `VBUS` | `+5V` | Red |
| `0` | `DI` | Green |
{% hint style="info" %}
On older Wemos D1 mini, pin `0` may be called `D3`.
{% endhint %}
# 3. Flashing
To program the LOLIN D1 mini, connect its USB-C port to a PC or Mac.
Then visit in Google Chrome, Microsoft Edge or Opera.
Afterwards, you can connect the device to Wi-Fi. From then on, it will install software updates automatically.
# Weather
An effect that sends your phone's location to Luxio, which polls for weather data and shows an effect based on the state (e.g. sunny, raining, thunderstorm etc.).
# Matter
At some point, Luxio should support Matter. At least for turning on/off, setting the brightness, and setting a solid color.
# Luxio Link
Luxio Link would be a technology where multiple Luxio devices could work together as one large LED strip. Imagine a multi-monitor setup, where every monitor is placed in a virtual space in relation to each other.
The first Luxio could control pixels 1 — 60, the second Luxio does 61 — 120 etc.
