APDS-9960 RGB and Gesture Sensor Hookup Guide



Touchless gestures are the new frontier in the world of human-machine interfaces. By swiping your hand over a sensor, you can control a computer, microcontroller, robot, etc. One manufacturer has even created a touchless toilet that flushes when you move your hand over the tank. The Avago APDS-9960 offers ambient light and color (as clear, red, green, and blue) measuring, proximity detection, and gesture sensing.

Avago APDS-9960 Breakout Board

The APDS-9960 RGB and Gesture Sensor board breaks out the pins on the Avago APDS-9960 so you can easily use it in a variety of projects. The APDS-9960 uses the I2C interface for communications.


If you do not have specifically a 3.3V Arduino Pro, there are a number of ways to complete the walkthrough. In general, you will need:

  • Arduino or other microcontroller – You will need something that is capable of I2C and communicating back to the computer (e.g. serial communications). The microcontroller needs to have a 3.3V I/O voltage or you will have to use a level shifter. We are using the 3.3V Arduino Pro, but the 3.3V Arduino Pro Mini would work as well.
  • Level shifting – If you are using a 5V Arduino, like the Uno or RedBoard, you will need to use a level shifter, such as the bi-directional logic level converter.
  • Connectors – You will need to interface your microcontroller with the breakout board. Male headers are perfect if you’re using a breadboard. Another option is to use wire to connect the breakout board directly to the microcontroller.
  • Soldering tools – After you’ve picked a connector, you will need to solder it to the breakout board. A simple soldering iron and some solder should be all you need.


Board Overview


Pin Descriptions

The APDS-9960 breakout board provides 6 pins to provide power to the sensor and I2C bus.

Front of APDS-9960 breakout board

Pin Label Description
VL Optional power to the IR LED if PS jumper is disconnected. Must be 3.0 - 4.5V
GND Connect to ground.
VCC Used to power the APDS-9960 sensor. Must be 2.4 - 3.6V
SDA I2C data
SCL I2C clock
INT External interrupt pin. Active LOW on interrupt event


Setting the Jumpers

On the front of the breakout board are 2 solder jumpers:

  • PS – This jumper connects the power supplies of the sensor and IR LED (also located on the APDS-9960) together. When the jumper is closed (i.e. connected), you only need to supply power to the VCC pin to power both the sensor and the IR LED. If the jumper is open, you need to provide power to both the VCC (2.4 - 3.6V) and VL (3.0 - 4.5V) pins separately. This jumper is closed by default.
  • I2C PU – This is a 3-way solder jumper that is used to connect and disconnect the I2C pullup resistors. By default, this jumper is closed, which means that both SDA and SCL lines have connected pullup resistors on the breakout board. Use some solder wick to open the jumper if you do not need the pullup resistors (e.g. you have pullup resistors that are located on the I2C bus somewhere else).

Hardware Hookup


Add Headers

Solder a row of break away male headers to the 6 headers holes on the board.

Solder headers onto board

Connect the Breakout Board

We will be using the Arduino Pro’s regulated 3.3V power and I2C bus with the APDS-9960. Note that we are leaving VL on the breakout board unconnected.

IMPORTANT: You must use 3.3V! If you try to use a 5V power supply or 5V I2C communications, you risk damaging the APDS-9960. If you are using a 5V Arduino (e.g. UNO), then you need to have some kind of level shifting.

Connect the breakout board to the following pins on the Arduino:

Arduino Library Installation

To use the APDS-9960, you will need some supporting software. If you are using an Arduino, then you are in luck! We created an Arduino library that makes the APDS-9960 easy to use. Click the button below to download the latest version of the APDS-9960 breakout board project, which includes the Arduino library.


Unzip the downloaded file and navigate to \APDS-9960_RGB_and_Gesture_Sensor-master\APDS-9960_RGB_and_Gesture_Sensor-master\Libraries.

Install APDS-9960 Arduino Library

Note: the directory names in this picture have changed slightly since the Arduino 1.6.3 update.

Follow this guide on installing Arduino libraries to install the files within the SparkFun_APDS9960 directory as an Arduino library.

Gesture Sensing Example


Load the GestureTest Example

Open up the Arduino program and select File → Examples → SparkFun_APDS9960 → GestureTest.

APDS-9960 GestureTest example

Plug in your FTDI Breakout (3.3V) to the Arduino Pro (3.3V). Attach a USB mini cable from your computer to the FTDI Breakout. If you have not previously done so, install the FTDI drivers.

Connect FTDI breakout board to the Arduino Pro

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

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!

Make sure you have the correct serial port selected under Tools → Serial Port and “Arduino Pro or Pro Mini (3.3V, 8MHz) w/ ATmega328” selected under Tools → Board. If you have never used the Arduino IDE before, this turoial should get you started.

Click the Upload button and wait for the program to finish uploading to the Arduino. Select Tools → Serial Monitor to open up the serial terminal. More info on the Serial Terminal can be found here. You should see a couple of messages noting that “APDS-9960 initialization complete” and “Gesture sensor is now running.”

APDS-9960 GestureTest initialization

Hover your hand 4 to 8 inches (10 to 20 cm) above the sensor but off to one side (i.e. not directly above the sensor). While maintaining the same height, swipe your hand over the sensor (into and then immediately out of range of the sensor). If you move too fast, the sensor will not recognize the gesture.


Gestures will appear on the serial monitor, which indicate the direction of the swipe.

APDS-9960 swipe directions

There are also 2 other gestures available: NEAR and FAR.

A NEAR gesture can be achieved by holding your hand far above the sensor (greater than 10 inches (25 cm)), bringing it close to the sensor (about 2 inches (5 cm) directly above the sensor), holding it there for at least 1 second, and then removing your hand.

A FAR gesture can be achieved by holding your hand directly above and close to the sensor (about 2 inches (5 cm)) for at least 1 second and then moving your hand up directly above and out of range of the sensor.

If a gesture was not correctly interpreted, NONE will appear in the serial monitor.

Other gestures supported by the APDS-9960

Supported Gestures

Here is a list of the currently supported gestures. Make sure each gesture begins outside of the range of the sensor, moves into the range of the sensor, and ends outside the range of the sensor.

Gesture Description
UP A swipe from the bottom of the board to the top and out of range of the sensor. Make sure that your wrist/arm is not in the sensor's range at the end of the swipe!
DOWN A swipe from the top of the board to the bottom and out of range of the sensor.
LEFT A swipe from the right side of the board to the left and out of range of the sensor.
RIGHT A swipe from the left side of the board to the right and out of range of the sensor.
NEAR Object (e.g. hand) starts far above the sensor, moves close to the sensor, hovers for at least 1 second, and moves out of range of the sensor.
FAR Object starts near the sensor, hovers for at least 1 second, and then moves up above and out of range of the sensor.
NONE The sensor could not correctly guess the gesture being performed.
