Day 9/37 Sensors Challenge | How does the KY011 Two Color LED Module show two colors with one LED ?

In today’s 37 Sensors Challenge, I used the KY-011 Two Color LED Module with Arduino UNO to switch between red and green using just one LED.

This simple module contains two LEDs inside a single package, making it a great project to understand how multi-color LEDs work.

Perfect beginner project to learn:
✅ Two Color LED Interfacing
✅ Digital Output Control
✅ LED Color Switching
✅ Arduino Programming Basics

Used in:
• Status indicators
• Signal systems
• Embedded prototypes
• DIY electronics projects

Tiny module. Two colors. Endless possibilities.
