APDS-9960 Gesture sensor with Arduino

Using this module in Arduino you can detect the gesture of your hand either UP, down, Left, Right and do something like controlling servo, motor or some other action.

This video and the following code will help you understand use the gesture sensor.
  1. APDS-9960 Library (getHub)
  2. APDS-9960 Library (from Robojax.com)
  3. APDS-9960 Data sheet (pdf)

 /*
 * Code for APDS-9960 Gesture sensor for Arduino
 * This code is to detect gesture of your hand either moving it up, down, left or right and other gestures
 * can be detected and used to control something else.

APDS-9960 RGB and Gesture Sensor

Tests the gesture sensing abilities of the APDS-9960. Configures
APDS-9960 over I2C and waits for gesture events. Calculates the
direction of the swipe (up, down, left, right) and displays it
on a serial console. 

To perform a NEAR gesture, hold your hand
far above the sensor and move it close to the sensor (within 2
inches). Hold your hand there for at least 1 second and move it
away.

To perform a FAR gesture, hold your hand within 2 inches of the
sensor for at least 1 second and then move it above (out of
range) of the sensor.

Hardware Connections:

IMPORTANT: The APDS-9960 can only accept 3.3V!
 
 Arduino Pin  APDS-9960 Board  Function
 
 3.3V         VCC              Power
 GND          GND              Ground
