Next, we need to open the ARDUINO IDE, and copy the following simple code to the IDE window. Then select the right serial port and board (Arduino UNO). Wave your hand in front of the sensor, see what happen on the serial port.

Sample Code

#include <Wire.h>
#include <SparkFun_APDS9960.h>

// Pins
#define APDS9960_INT    2 // Needs to be an interrupt pin

SparkFun_APDS9960 apds = SparkFun_APDS9960();
int isr_flag = 0;

void setup() {

  // Initialize Serial port
  Serial.begin(9600);
  Serial.println();
  Serial.println(F("--------------------------------"));
  Serial.println(F("APDS-9960 - GestureTest"));
  Serial.println(F("--------------------------------"));

  // Initialize interrupt service routine
  attachInterrupt(0, interruptRoutine, FALLING);

  // Initialize APDS-9960 (configure I2C and initial values)
  if ( apds.init() ) {
    Serial.println(F("APDS-9960 initialization complete"));
  } else {
    Serial.println(F("Something went wrong during APDS-9960 init!"));
  }

  // Start running the APDS-9960 gesture sensor engine
  if ( apds.enableGestureSensor(true) ) {
    Serial.println(F("Gesture sensor is now running"));
  } else {
    Serial.println(F("Something went wrong during gesture sensor init!"));
  }
}

void loop() {
  if( isr_flag == 1 ) {
    handleGesture();
      if(digitalRead(APDS9960_INT) == 0){
      apds.init();
      apds.enableGestureSensor(true);
    }

    isr_flag = 0;
  }
}

void interruptRoutine() {
  isr_flag = 1;
}

void handleGesture() {
    if ( apds.isGestureAvailable() ) {
    switch ( apds.readGesture() ) {
      case DIR_UP:
        Serial.println("UP");
        break;
      case DIR_DOWN:
        Serial.println("DOWN");
        break;
      case DIR_LEFT:
        Serial.println("LEFT");
        break;
      case DIR_RIGHT:
        Serial.println("RIGHT");
        break;
      case DIR_NEAR:
        Serial.println("NEAR");
        break;
      case DIR_FAR:
        Serial.println("FAR");
        break;
      default:
        Serial.println("NONE");
    }
  }
}

Result

Wave your hand in front of the sensor, see what happen on the serial port.

Additional Information

This sensor not only support gesture recognition, but also the range, ambient light and RGB color detecting. The specific examples can be found in the library EXAMPLES folder. so you can also develop other application according to your requirement.
