The KY-011 Two Color LED module emits red and green light. You can adjust the intensity of each color using PWM.
This module consist of a common cathode 3mm red/green LED, a 0Ω resistor, and 3 male header pins. Since the operating voltage is between 2.0v and 2.5v, you’ll have to use limiting resistors to prevent burnout when connecting to the Arduino.
