• Vibrant ring of 24 RGB LEDs
• Can be sewn or soldered
• Great for all light projects and wearables
• Can be easily controlled and dimmed using an Arduino
• Uses a single digital pin
• 3v – 9v powered
• Arduino library available hereWhy pick the NeoPixel Ring – 24?
If you’re looking to make an ornamental LED project, or light an area with a colour of your choice with easy application, this NeoPixel ring is right for you. With 24 individually controllable LEDs assorted in a ring you can get them to show their own colours and flash at their own times, or get them to work in tandem. Use the Ring – 24 as a DSLR light or a digital clock with an analogue feel. All of this can be done using power and only one digital pin.
In addition, a Adafruit FLORA will fit perfectly inside the Ring – 24.
What is a NeoPixel?
A NeoPixel is a 5mm by 5mm square LED that can host 24-bit colour. To put that in perspective that’s 16,777,216 different shades of colour available to you with each LED, mixing red, green and blue. They use built-in drivers so there’s minimal preparation and next to no coding required to get going.
Another thing to keep in mind is that you can speak to all the LEDs individually, telling them what colour and brightness to display. They also ensure no matter how many LEDs are active or changing, you will always get the same quality of colour, and the same brightness throughout.
These NeoPixels only require 3v – 9v to power and at full brightness use 60mA per LED. In addition to this you only need to use one digital pin to control a range of NeoPixels, making it very easy to implement into any project. You can find out even more about NeoPixels and best practice here.
What library will I need to use?
NeoPixels can be easily controlled using Adafruits NeoPixel library available here. An Arduino library allows quick and easy programming for a vast range of projects. In the case of the NeoPixel library, it allows you to quickly manipulate any number of NeoPixel LEDs individually.
