• Vibrant quarter ring of 15 RGB LEDs
• Soldering required
• Great for larger light projects
• Uses a single digital pin
• 3v – 9v powered
• Four are required to make the larger 60 LED ringWhy pick the NeoPixel ring – quarter 60?
If you are looking to make a larger lighting display or a wearable headpiece, the NeoPixel ring – quarter 60 is right for you. Each quarter 60 ring will come with 15 RGB LEDs and you’ll need four of these to make the larger 60 LED ring. This is perfect if you choose to design a clock, choose to add the smaller NeoPixel and have an hour, minute, and second hand.
If you do not make a circle and instead decide to make other shapes, the only limit to how many you can link is based on how much RAM your Arduino controller has.
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.
