Description
The KY-029 Bi-Colour LED Module features a two-colour red and green LED in a single package, allowing you to create red, green, or yellow (red + green) light using simple digital outputs from an Arduino, Raspberry Pi, or any microcontroller.
This compact module is ideal for status indicators, visual alerts, colour mixing demonstrations, or creative lighting effects. It’s easy to use and integrates seamlessly into breadboards and DIY electronics projects.
