## Description

This LED Is super *chonky!* Bigger than your average LED, it has a big, bold, and beautiful diffused body that measures approximately 18mm diameter. Inside is nestled a bi-color red and green LED, just like you're familiar with. Each with about 2.3V forward voltage. Add a resistor in series and connect to a battery or microcontroller pin for a gorgeous glow. The center pin is the common cathode, so connect that to ground, then use the two outer pins to control the red and green elements inside.

Could be a great addition to a control panel, cosplay, or art project. They go easily into a breadboard and will add that extra cool zing to your project.

If you need some help using LEDs, please read Adafruit's "Introduction to using LEDs" tutorial for any electronics project.
