Adafruit 100226 24 RGB Neopixel LED Ring with Integrated Drivers

Excellent product from Adafruit - well thought out and bright product. It works straight out of the box once plugged into your Arduino/micro controller. Outer edge to edge is 65mm and the gap in the middle is 52mm. I found it hard finding online the dimensions to help fit an LCD in the middle of the ring.This is the 24 pixel ring and its perfect size for the project im currently making (GPS speed gauge with LED visual speed display). It would be nice if there were some half sizes, for example, this is the 24 ring and the next size up is 60 LED.. which is quite a big jump.Top tip is set brightness to low when using as this thing is seriously bright. Arduino = " strip.setBrightness(10); "Overall Adafruit make some incredible, well thought, well made products and i would say in 99% of the projects i make you can usually find something in there made by Adafruit!

Very nice neopixel ring and they are genuine Adafruit.Easy to use with Arduino, all libs and examples available on Adafruit and in Arduino IDE (just look for Neopixels in Library manager).I'll be using these as a backlight to a water feature assuming I don't give into the urge to buy another and make a pair of specs.Having regressed back to childhood, I now find myself in love with Neopixels! They are just full of sparkly goodness.

These are very pretty and it’s easy to programme them if you’re familiar with arduino. However for some bizarre reason the connectors are distributed around the ring (8 of them) rather than being all together in one place. This makes it hard to come up with a neat wiring solution.

This ring is beautiful, with perfect colours, unlike some of the cheaper RGB lights I've used in the past where you can see the separate colours. With Neopixels the colours blend together really well.Note that this ring can be incredibly bright. I mean bright enough that you wouldn't want to look directly at it for very long. I suggest setting your brightness to a low number, for example 5, while you're working with it.Also another thing to note is that at full brightness each diode can consume 18mA each, so 18mA * 3 diodes * 24 pixels = 1.3 amps. You need to ensure you have a separate power supply when working at full brightness, you wouldn't want to drive these directly through your microcontroller.

Simply soldering on 3 wired, plug into an arduino and it's super simple to program! The LEDs are incredibly bright and it has a very smooth operation, highly recommended if you like to tinker.

Works just great with Arduino and ATTiny85 (running Arduino test code).Note not compatible with all Raspberry Pi' s (all the Pi's I tried) Next job is to make the AtTiny interface to my Pi.

Would definitely buy again. Great light, the colours are fantastic! Will be buying more.

Pretty much impossible to solder wires onto the tiny connection points provided. I had problems with other manufacturer neopixels and hoped that because the holes were much further apart the soldering would be easy, this wasn't the case.

One tip for getting it to work is to make sure the power voltage matches the signal voltage. In my case, it was 3.3v each. I used the basic Adafruit library (adafruit/Adafruit_NeoPixel on Github). The Adafruit site had enough info to get me up and running.

These are simple to use, robust and have been reliable. They're tough to mount though having no ears or tabs.They're a little bright for annuciators at night even at the dimmest setting that'll still display white (3). These are rgb so to make white you turn on all 3 colors with equal intensity. You can control the color of each one individually but not the brightness, that's global. They are strobed to conserve power and it works - all 24 lit green plus the arduino micro plus a 7 segment backpack only takes 40-50ma.

Consegnato in perfetto stato, impeccabile servizio spedizione amazon.Passiamo al prodotto: compatto, non grandissimo come dimensioni e si presenta con un bel aspetto estetico per montaggio anche a vista. Ovviamente non è stagno,quindi è obbligatorio montarlo all'interno,o in posti dove non presenta acqua. Misure di circonferenza interna 4,8 cm; circonferenza esterna 6,3 cm. Led con montaggio superficiale in SMD ed il numero presente sull'anello sono 24 elementi RGB ad alta illuminazione. Nella circonferenza dell'anello si vedono dei fori con cablaggio da realizzare con saldatore e stagno per collegamento 5V-GND-IN. Presenti anche altro trio di fori per collegamento 5V-GND-OUT ad un altro anello.Il prezzo può sembrare alto,ma credo che ne vale in tutto,per la qualità in se per se del prodotto e la compatibilità tramite librerie Neopixel Adafuit con Arduino. Acquistato per ristrutturare piantana con una lampada ad incandescenza, si possono creare oltre ad una luce " fredda" o "calda" anche effetti RGB.

très pratique et très joli une fois qu'on sait équilibrer les couleurs.

gute Qualität - zum Basteln gut geeignet. Wollen jetzt in einem Projekt das ganze in einen Schreibtisch einbauen....
