LED 3mm 3-Pin Common Anode Red & Yellowish-Green Dual LED
The LED 3mm 3-Pin Common Anode Red & Yellowish-Green Dual LED is a compact dual-color indicator LED designed for multi-state signaling. With a common anode configuration, this LED combines bright red and yellowish-green emitters in a single 3mm lens, making it ideal for status indication, embedded systems, and control panels. Its low power consumption and clear illumination make it reliable for professional and hobby electronics projects.

How to Use
- Identify the common anode pin (usually the longest pin).
- Connect the anode to the positive supply (VCC).
- Connect a current-limiting resistor (330E–1K) to each cathode pin.
- Ground the red cathode to illuminate red.
- Ground the yellowish-green cathode to illuminate green.
- Pulse both pins to create mixed or blended color effects.
