# Grove 3 Axis Digital Gyro

![](https://raw.githubusercontent.com/SeeedDocument/Grove-3-Axis_Digital_Gyro/master/img/Grove-3-Axis_Digital_Gyro.jpg)

Grove - 3-Axis Digital Gyro module based on ITG 3200. It is the world’s first single-chip, digital-output, 3-axis MEMS motion processing gyro optimised for gaming, 3D mice, and motion-based remote control applications for Internet connected Digital TVs and Set Top Boxes. The ITG-3200 features three 16-bit analog-to-digital converters (ADCs) for digitising the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface.

## Platforms Supported

## Demonstration

This demo will show you how to get data from this digital gyro, the data is in the unit of rad/s.

Here we need a Grove - 3-Axis Digital Gyro and a Seeeduino V3.0.

### Hardware Installation

Hardware installation is very easy, because there's an I2C Grove in Seeeduino,

So, what we need to do is connect it to I2C Grove via a Grove cable.

### Download Code and Upload

You can download the library in github, click [here](https://github.com/Seeed-Studio/Grove_3_Axis_Digital_Gyro/), then extract it to libraries folder of Arduino.

Then open File -> examples -> Grove\_3\_Digital\_Gyro -> ITG3200\_gyro, you can open the demo code.

Click Upload to upload the code, if you have any problem about how to start Arduino, please click [here](https://app.gitbook.com/Getting_Started_with_Seeeduino) for some help.

### Check the result

Now, you can open the serial monitor to check the result.
