Ring with 24 RGB WS2812 LEDs and integrated driver
Neopixel ring with 24 RGB LEDs that can be individually controlled, each of which can produce 256 shades of its color, resulting in a total of 16,777,216 colors.
Overview
The data channel for communication is a One-Wire serial type and can be controlled with microcontrollers like Arduino.
You can set the refresh frequency as desired to make certain light effects imperceptible. Multiple rings can be cascaded together to create various effects.
Tech specs
Power supply: 5 Vdc.

It can be tough to get started with building an Internet of Things (IoT) project from the ground-up, as getting connected, serving a webpage, and managing other devices can all be a challenge to a beginner. This is why the YouTuber known as “Mario’s Ideas” made an end-to-end tutorial that details everything one might need to build a smart RGB lamp. Because the Arduino UNO R4 WiFi contains an ESP32-S3 chip for its Wi-Fi radio and Renesas RA4M1 microcontroller, it was the perfect candidate. Mario’s sketch begins with a call to initialize the Wi-Fi module before attempting to connect to his local access point. Once finished, it enters a loop that continuously checks if a client has connected to the web server, and if one has, reads the requested path while also seeing if the string contains “/H” to denote an “ON” command to set the LED. Toggling an LED is useful, but Mario wanted to take things a step further by building a tangible — in this case a lamp. His 3D-printed enclosure features a recessed base and translucent cube for diffusing the light emitted by a grid of NeoPixels. Controlling the color was just as easy since any browser could still send a request path containing a color and get back the lamp’s updated status.
