Esta solución se integra a la perfección con software popular como WLED y xLights, lo que la convierte en una opción ideal para una amplia gama de aplicaciones de iluminación.

Light Lab allows you to experiment with different patterns on RGB LED NeoPixel (WS2812 or WS2812B) or DotStar (APA102 or SK9822) strips. It has a display that lets you choose one of several different patterns from a menu, and provides three interactive controls to allow you to vary the parameters of each pattern: Light Lab lets you drive NeoPixel or DotStar strips with attractive customisable light patterns. There are 22 different built-in patterns catering for LED strips, rings, and matrices, and you can easily add your own. Most of the patterns use fractional calculations to provide smooth gradations of colour and brightness. Light Lab can be powered from USB-C, a 5V power jack, or an internal protected 18650 Lithium cell. It supports NeoPixel (WS2812 or WS2812B) or DotStar (APA102 or SK9822) LED displays with up to 160 RGB LEDs. Introduction I've recently been experimenting with driving NeoPixel displays using the peripherals in DA, DB, and DD series AVR microprocessors, and this set me to thinking about what would an ideal platform for designing and experimenting with NeoPixel displays. The idea was to create something like my sound synthesiser, Sound Lab - a Simple Analogue Synthesiser, but for coloured RGB LEDs. This led to Light Lab, which has the following features: A controller that will drive a strip, ring, or matrix of NeoPixel (WS2812 or WS2812B) or DotStar (APA102 or SK9822) LED displays. Three potentiometers that allow you to interactively vary three parameters of each pattern. A large 2.42" 128x64 OLED display that displays information about each pattern, and labels the three potentiometers with legends and the current settings. Up and down buttons that allow you to step between the alternative patterns. An on/off switch, to turn on or off Light Lab. Three alternative power options: USB-C, a 5V power jack, or a protected 18650 Lithium cell. A STEMMA QT I2C connector, to allow you connect an I2C sensor (for future expansion). It's based on an AVR128DB28 processor, in conjunction with a CP2102N USB-to-Serial converter to allow you to upload new firmware via the USB-C port. Using Light Lab Once you've built Light Lab and uploaded the program as described later in the article, here's how you use it. Connecting an LED strip The first step is to connect a NeoPixel (WS2812 or WS2812B) or DotStar (APA102 or SK9822) LED display to the screw terminals at the right of the board. It can be a strip, circle, or any other configuration. Connect the GND wire (usually black) to the GND terminal, and the 5V wire (usually red) to the +5V terminal. If you're connecting a NeoPixel strip, connect the DI (Data In) wire (often green) to the D1 terminal. The D2 terminal is unused: Connecting a NeoPixel LED strip. If you're connecting a DotStar strip, connect the CI (Clock In) wire (often yellow) to the D1 terminal, and the DI (Data In) wire (often green) to the D2 terminal: Connecting a DotStar LED strip. Switching on for the first time When you first use Light Lab: Switch on while pressing the DOWN button to display the Settings screen: You can then specify the settings you want to use: Turn the Type control to specify the type of LEDs you are using, DotStar, Neo GRB (NeoPixels with GRB pixel order; most common), or Neo RGB (NeoPixels with RGB pixel order). Turn the LEDs control to specify the number of NeoPixels or DotStars connected to Light Lab. There is a choice of the most common options, from 30 to 160 LEDs. Turn the Bright control to specify the maximum brightness; this can be one of the values 6%, 12%, 25%, 50%, or Max (100%). Press the UP button to exit from Settings. The settings are remembered even when power is disconnected from Light Lab. You can change the settings at any time by holding the DOWN button when switching on. Note that if you accidentally select the wrong LED type or number of LEDs you may get an incorrect display, but it won't cause any harm to the Light Lab or LEDs. The main screen The main screen shows the settings, current pattern, and the function and value of each of the controls: The Light Lab screen showing the settings, current pattern, and control functions and values. The top line shows the settings (LED type, number of LEDs, and global brightness), and the voltage at the LED output. When powered by the USB port the voltage will be about 0.2V below the expected 5V because of the Schottky diode protecting the output. When powered by a lithium battery the voltage will be between 4.2V and 3.2V as the battery is depleted. The centre lines show the name of the pattern, and a description. The bottom two lines show the function of each control, and the current settings. Depending on the pattern the Speed control may go from 0% to 100% or from -50% to 50%. The other settings go from 0% to 100%. On the right-hand side of the screen is a scroll bar showing your current position in the list of patterns. Selecting a pattern Press the UP or DOWN button to step between the available patterns. Adjusting the pattern Turn each of the controls to achieve the effect you want. Blanking the display If you don't want the light from the display to interfere with the effect of your RGB LEDs you can blank it as follows: Press the UP and DOWN buttons together. To turn it back on press the UP and DOWN buttons together again, or select a different pattern. Other LED displays Although this article talks about LED strips, Light Lab can be used with RGB displays arranged in other layouts. Here are a couple of examples: NeoPixel Rings: A range of NeoPixel rings in different sizes are available from Adafruit and AliExpress. For example, 12 RGB NeoPixels [1], 16 RGB NeoPixels [2], 24 RGB NeoPixels [3], and 60 RGB NeoPixels [4]. Of the moving patterns the following are ideal for use with rings as they join up seamlessly: Colour Waves, Twin Peaks, Theatre Lights,
