Arduino_KY-029_Yin_Yi_2-color_LED_module_3MM

Arduino KY-029 Yin Yi_2-color LED module 3MM

Same as KY-011 only different led size
Additional needed 330 Ohm resistor ( 2x)

On my version only the red led functioned the other was defective !

Hardware

• 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 perhaps can work without the 330 Ohm resistor, however it is strongly recommended to add the resistors!
