The components

I didn't draw any schematics, since it's all about just plugging one component with 4 male pins into another component with 4 female pins. Locate the GND or "-" pin of the KY-016. This goes into the GND pin of the UNO, next to digital pin 13. Don't bother if the red, green and blue pins of your KY-016 are in another order, as long as they go to pins 11 to 13 and the GND or "-" pin goes to the GND of the UNO.
