Arduino_KY-011_2-color_LED_module

KY-011 37-1 2-color LED module

Led with red and green color

Additional needed 330 Ohm resistor ( 2x)

Hardware connection

  • Arduino pin 10 --> resistor 330 Ohm --> Signal pin of the module   (Green)
  • Arduino pin 11 --> resistor 330 Ohm --> Middel pin of the module  (Red)
  • Arduino GND  --> module -/GND


The circuit will work without the 330 Ohm resistor, however it is strongly recommended to add the resistors!
