If the 4th argument is 1 or true then it outputs an array which can be used with Uint8Array.Have you been asking yourself how you can connect one LED strip to another? In this article, we are going to elaborate on LED accessories and how to use them. You can also use E.HSBtoRGB to convert hue values into RGB. If you used Uint8Array instead than a value would just have the top bits removed, turning 256 into 0, 257 to 1 and so on. Using Uint8ClampedArray also means that any values greater than 255 or less than 0 are 'clamped'. If you want to control more LEDs (for instance the whole string), we'd recommend using an ArrayBuffer for speed, and to save on memory. Require("neopixel").write(B15, ) // turn first 3 LEDs, Red, Green, and Blue require("neopixel").write(B15, ) // turn first LED Red The first 3 bytes are red, green and blue for the first LED, the second are for the second LED, and so on.

To control the LEDs, just send a series of bytes to them.
Note: This is currently covered in the Individually Addressable LEDs tutorial. The only condition is that the data wire is connected to an SPI MOSI port on the Espruino Board: LED StringĬHECK YOUR WIRING AND DO NOT WIRE UP THE VOLTAGE BACKWARDS - WS2811 chips are quite delicate and the entire string of lights can be easily blown up by doing this. Included in the kit should be a matching connector so that you can plug and unplug the LED string. While you can often peer through the casing to see the letters DI (Data In) or DO (Data Out), if you have the LED Strings from the Espruino Kits then the end you need is the 'Female' end (the one without the visible metal spikes in the plug). WS2811-based LEDs need just 3 wires, however because they're a string (and can be chained together), they have two ends. Using the Original Espruino and Pico is easy, but other boards may require a little more thought. Wiring UpĬheck out the neopixel library reference - WS2811 style LEDs can be quite picky about the voltage of the data wire. In the LED strings, the WS2811 controller chip is separate to the LED (you can see it as the black blob encased in plastic).

Part NumberĪ separate SOIC8 LED driver chip - often used in LED strings. Note that while physically different (some are built into LEDs, some are separate chips), the WS2811/WS2812/WS2812B/APA104/APA106/SK6812 all work the same way electrically. They come in many different forms - LED Strings (like above), LED Strip, Matrices like Adafruit's NeoPixels or the RGB123, or even 5mm LEDs. These are individually addressable RGB LEDs - this means with just 3 wires, you can make each LED turn any one of 16 million colours.
