OUTPUT: How to check ?
1. Go to sketch
2. Next is include libraries --->manage libraries----> search for (APDS9960) ------> select(SPARKFUN APDS9960 RGB AND GESTURE SENSOR)see if is installed or not .
3.If not installed, install with all libraries.
4. If it is installed with all libraries then ---> in the include libraries Search for
SPARKFUN APDS9960 select it and upload to the arduino board.
