What is Arduino®
Arduino®is an open-source prototyping platform based on easy-to-use hardware and software.
Arduino®boards are able to read inputs –light-on sensor, a finger on a button or a Twitter message –
and turn it into an output –activating of a motor, turning on an LED, publishing something online. You
can tell your board what to do by sending a set of instructions to the microcontroller on the board. To
do so, you use the Arduino programming language (based on Wiring) and the Arduino®software IDE
(based on Processing). Additional shields/modules/components are required for reading a twitter
message or publishing online. Surf to www.arduino.cc for more information

Product overview
This sensor is able to detect 9 distinct gestures like up, down, forward, backward, rotating, ... to use as an
input for your project. Check out all gesture possibilities in the features below. The module interfaces to
your development board (e.g. Arduino® compatible board) using I²C and is able to detect and report various
gestures including moving up, down, left, right, forward, backwards, rotating clockwise and anti-clockwise,
and waving.
The module has a normal and game mode that can read your gestures at a different speed. The detection
distance is 10 cm and the ambient light immunity is <100k lux. This module has a 12C interface that is easy to
interface with microcontroller boards.
Specifications:
Supply voltage: 5 V DC
Working current: 50 mA
Max. power: 0.5 W
Detection distance: 10 cm max.
Gesture speed: 60 °/s –600 °/s (in normal mode), 60 °/s –1200 °/s (in game mode)
Ambient light immunity: < 100k lux
I²C communication speed: max. 400 kbit/s
Working temperature range: -25 - +65 °C
Interface connector: standard 5-pin pin header
Dimensions (W x L x H): 35,5 x 20,1 x 7 mm

Example program
1. Use the Arduino Library manager to install the RevEng PAJ7620 library, by going to Sketch
> Include Library > Manage Libraries… , typing in paj7620 in the search bar, selecting the
correct library, and clicking “Install”:
2. Open the paj7620_9_gestures example sketch from the library you installed by going to
File > Examples > RevEng PAJ7629 > paj7620_9_gestures
3. Connect your Arduino compatible board, make sure the correct Board and connection port
are set in the tools menu, and hit Upload
4. Open the serial monitor by clicking the serial monitor button , make sure the baudrate is
set at 115200 baud. Try some gestures out in front of the sensor and they should appear on
the serial monitor!
