RGB led module

The KY-009 is a small breadboard-friendly RGB LED module mounted on a small PCB making it very versatile. Using the Arduino PWM function almost any color can be created. Limiting resistors are required when connecting to Arduino pins.

Recommended Current Limiting Resistors and Wiring:

• R - Red: 180 Ohm resistor
• G - Green: 100 Ohm resistor
• B - Blue: 100 Ohm resistor
