Product information:
With this 4-piece set you can make a ring with 40 WS2812 RGB LEDs.
The segments can be interconnected (soldered), so that all 40 LEDs can be controlled individually with 1 signal pin from an Arduino/Raspberry Pi or other MCU.
For example, you can make a clock this way.
Download the Adafruit Neopixel library or FastLED library for programming examples.
