This is a Neopixel technology ring with 12 RGB LED diodes that can be individually controlled, each of which can produce 256 shades of its own color, resulting in a total of 16,777,216 colors. The data channel for communication is a One-Wire serial type and can be controlled with microcontrollers such as Arduino, PIC, mbed, etc. You can set the refresh frequency as desired, so as to make certain light effects imperceptible. Multiple rings can be cascaded together to create various effects. Power supply: 5 Vdc.
