For this I found an Adafruit library "Adafruit_APDS9960-master.zip". But it will not work.
The example for proximity ends with no luck, it gives an error form the library (object.begin()) "failed to initialize device! Please check your wiring." That looks like a problem with I²c.
I edited the sketch to give more information, it endet up with the typical COMx chaos and i give up for today.
I'm hoping for a better integration of this very interesting board into the Arduino IDE.
