Digital RGB LEDs like the Neopixel are greatfor creating awesome lighting effects. But keeping them responsive to user inputs at the same time can be challenging. And what if you want to have different parts of your project animated in different ways? In this guide, we'll explore techniques to make your pixel patterns lively, flexible and responsive.
NeoPixel LEDs are the bee's knees, but in a few scenarios they come up short…connecting odd microcontrollers that can’t match their strict timing, or fast-moving persistence-of-vision displays. Adafruit DotStar strips deliver high speed PWM and an easy-to-drive two-wire interface, bridging the gaps in the spectrum of awesome.
A PIC is used as a SPI Master to create a simple interface to up to 21845 NeoPixels. After being configured with the number of attached NeoPixels the Pixif continuously retrieves the RGB values via SPI and generates the NeoPixel GRB bitstream. The update rate may be throttled via a synchronization input. This approach frees the host processor to concentrate on its algorithms especially when its SPI Slave has DMA support.
If you're like me, you loved the Adafruit Daft Punk helmet that showed up on our blog a few weeks ago... but, as my 3D printer is a little bit smaller than a TAZ, and funds and time are limited, I thought for Halloween I would make my own version, based around a $5 mask from Party City that looks a little bit like Cobra Commander.
What your new apartment really needs is an upgrade to that beaded curtain - why not liven it up with a massive 1,500-LED NeoPixel curtain? NeoPixels + Raspberry Pi + Fadecandy == AWESOME! This project will show you how you too can build this massive and enjoyable flexible display. If you're interested in any other kind of large-scale NeoPixel project, this guide will help with all your detailed questions with Phil Burgess' hard-earned tips and techniques.
Adafruit’s Bluefruit devices are hands-down the easiest way to get Arduino communicating over Bluetooth. Taking inspiration from the helical Guggenheim museum, this project coils a contiguous reel of NeoPixels around a dapper top hat to create a wearable scrolling message display you can control with your iOS/Android phone or tablet.
Basketball hoop lights usually aren't very good. They are usually one not very bright color. Not anymore! With NeoPixels and Gemma you can program these basketball hoop lights to be a certain color or change colors. Besides, NeoPixels are much brighter than a few LEDs! We even add a sensor so it will light up when you score a point
Light painting is an artistic medium combining light, motion and long-exposure photography. For as long as a camera’s shutter is open, a single point of light in motion will create a continuous streak in the final photograph. Digital technology takes light painting to the next level…dozens of point lights, with color and brightness individually under computer control, weave a swath of awesome across the completed frame. Adafruit’s NeoPixel strips, combined with the Arduino microcontroller and a supporting cast of parts, make highly refined digital light painting achievable!
