It can recognize 9 basic gestures ,and these gestures information can be simply accessed via the I2C bus. Application: You can use Gesture as an input device to control another grove, or a computer, mobile phone, smart car, robot, and more with a simple swipe of your hand.

9/25/2015 Grove Gesture v1.0 Wiki 2 Built-in proximity detection 3 Various main boards support : Arduino UNO/Seeeduino/Arduino Mega2560 Specification Sensor PAJ7620U2 Power supply 5V Ambient light immunity < 100k Lux Gesture speed in Normal Mode 60°/s to 600°/s Gesture speed in Gaming Mode 60°/s to 1200°/s Interface type IIC interface up to 400 kbit/s Operating Temperature -40°C to +85°C Dimensions 20 * 20mm Detection range 5-15mm With Arduino/Seeeduino Suggest Reading for Starter Download Arduino and install Arduino driver (http://www.seeedstudio.com/wiki/Download_Arduino_and_install_Arduino_driver) Getting Started with Seeeduino/Arduino (http://www.seeedstudio.com/wiki/Getting_Started_with_Seeeduino) Hardware Installation Grove products have a eco system and all have a same connector which can plug onto the Base Shield (http://www.seeedstudio.com/wiki/index.php?title=Base_shield_v2&uselang=en) . Connect this module to the I2C port of Base Shield, however, you can also connect Grove - Gesture to Arduino without Base Shield by jumper wires.

- Page 5 9/25/2015 Grove Gesture v1.0 Wiki Gesture Library We have created a library to help you start playing quickly with the Seeeduino/Arduino, in this section we'll show you how to set up the library and introduce some of the functions. Setup 1. Download the library code as a zip file from the Gesture_PAJ7620 github page. (https://github.com/Seeed-Studio/Gesture_PAJ7620) 2. Unzip the downloaded file into your …/arduino/libraries. 3. Rename the unzipped folder "Gesture"(or:"Gesture_PAJ7620") 4. Start the Arduino IDE (or restart if it is open). Simple Demo The following simple demo will show you a very easy application: When you move up, the red led will be turned on, otherwise the red led will be turned off. #include <Wire.h> #include "paj7620.h" http://www.seeedstudio.com/wiki/Grove__Gesture_v1.0 5/10...
