Arduino Arduino_APDS9960 - readColor()用法及代码示例

Int r, g, b;
APDS.readColor(r, g, b);
Int a;
APDS.readColor(r, g, b, a);

/*
  APDS-9960 - Color Sensor

  This example reads color data from the on-board APDS-9960 sensor of the
  Nano 33 BLE Sense and prints the color RGB (red, green, blue) values
  to the Serial Monitor once a second.

  The circuit:
  - Arduino Nano 33 BLE Sense.

  This example code is in the public domain.
