Gesture Detection with APDS9960

Objective

This experiment uses the APDS9960 sensor to detect gestures, such as up, down, left, and right.

Required Components

• APDS9960 Gesture Sensor
• Arduino Board (e.g., Arduino Uno)
• Jumper wires
• Breadboard

Working Principle

The APDS9960 sensor uses infrared light to detect gestures by measuring the reflected light from the user's hand movements.

    while (1);
  }
  apds.enableGestureSensor(true);
}

void loop() {
  if (apds.isGestureAvailable()) {
    int gesture = apds.readGesture();
    switch (gesture) {
      case APDS9960_UP:
        Serial.println("Gesture: Up");
        break;
      case APDS9960_DOWN:
        Serial.println("Gesture: Down");
        break;
      case APDS9960_LEFT:
        Serial.println("Gesture: Left");
        break;
      case APDS9960_RIGHT:
        Serial.println("Gesture: Right");
        break;
      default:
        Serial.println("No Gesture");
        break;
    }
  }
}
            

Results

The serial monitor will display the detected gesture based on the hand movement.

Applications

• Gesture-based control systems
• Home automation
• Interactive displays

Conclusion

The APDS9960 sensor is a useful tool for detecting hand gestures, enabling applications in motion control, automation, and user interaction systems.
