Neopixel ring with 12 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

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.

Easily build an energy meter with the Arduino Nano Matter
Easily build an energy meter with the Arduino Nano Matter
September 24, 2024

The primary appeal of microcontrollers is their versatility. They are, essentially, the embedded equivalent of computers — general purpose devices that can perform a wide range of functions. And to get the most out of a microcontroller, you’ll also want connectivity suitable for your application. That’s why we released the Arduino Nano Matter and YouTuber Mr Innovative has shared a great video illustrating how easy it is to build an energy meter using this new development board. The Nano Matter is based on the powerful Silicon Labs MGM240S, which has an Arm Cortex-M33 processor and support for a number of wireless connectivity options, including 802.15.4 (Zigbee and Thread), Bluetooth® Low Energy 5.3, Bluetooth® Mesh, and Matter. That makes the Nano Matter perfect for smart home and other Internet of Things applications. To demonstrate that, Mr Innovative created an energy meter that would be useful to many people around the world. This unit monitors the power flowing to any device or appliance connected to mains AC power. It displays information about that power consumption on a small OLED screen, and also sends the data over Bluetooth to a connected smartphone for logging. The Nano Matter can’t monitor mains AC voltage directly, so Mr Innovative used a ZMCT103C current transformer for the job. The Arduino receives its power from a 9V battery and the components fit inside a 3D-printed enclosure. A printed sticker label gives that a nice, smooth top finish.
