Grove - Circular LED
This is a unique ring– it has a orid body with 24 controllable LEDs.
Maybe it will drive the inspiration out of you to make a glowing
magic ring! There is a 1*1 square hollow-out in the middle of this
module, where you can place a Grove Encoder in and make it a
rotary visual encoder!
