A great new guide in the Adafruit Learning System today: the NeoPixel NanoRing by Amelia.
Create a delicate ring of NeoPixels attached to a Gemma bracelet. Program your ring in Arduino, CircuitPython, or with MakeCode Maker & then protect your NeoPixels by encasing them in resin.
This guide uses an Adafruit Gemma M0 and Nano RGB LEDs. The Gemma M0 should be used with the onboard dotstar LED, capacitive touch sensors, and ability to program using CircuitPython or MakeCode Maker.
Nano RGB LEDs are a quarter of the size of standard 5050mm NeoPixels you may be used to seeing. They’re tiny and adorable and once encased in resin, will be both durable and waterproof. Although these LEDs are not really meant for hand soldering, each LED has a teeny tiny pad that can be carefully soldered to.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
