Grove LED Bar V2.0 – MY9221 with 10 Segment – Seeed Studio

The Grove LED Bar V2.0 is a versatile 10-segment LED indicator module powered by the MY9221 LED driver chip, designed to display gradients, levels and dynamic effects with ease. Each of the ten LEDs can be controlled independently, allowing developers to create smooth progress bars, visual meters and interactive light patterns. The bar includes four vibrant colours—red, yellow, light green and green—providing clear visual differentiation for status levels or multi-stage indicators. With its Grove plug-and-play interface, the module connects seamlessly to Arduino, Raspberry Pi and other Grove-enabled boards without complex wiring or soldering. Ideal for battery level indicators, water or volume meters, sensor value displays, and creative visual projects, the Grove LED Bar V2.0 delivers reliability, flexibility and eye-catching illumination.

Key Features
 
  • Interesting Progress Bar: Ten LEDs illuminate sequentially like flowing water, ideal for dynamic gradient displays.
  • Four-Colour Visual Output: Red, yellow, light green and green segments create multi-colour step indicators.
  • Flexible LED Control: Each of the 10 segments can be individually addressed and programmed.
  • Grove Unified Socket: Simple plug-and-play integration with no soldering, perfect for rapid prototyping.
