The shield can be purchased at the main site: <http://www.circuitsathome.com/products-page/arduino-shields> or from [TKJ Electronics](http://tkjelectronics.com/): <http://shop.tkjelectronics.dk/product_info.php?products_id=43>.
First download the library by clicking on the following link: <https://github.com/felis/USB_Host_Shield_2.0/archive/master.zip>.
Then uncompress the zip folder and rename the directory to "USB\_Host\_Shield\_20", as any special characters are not supported by the Arduino IDE.
Now open up the Arduino IDE and open "File>Preferences". There you will see the location of your sketchbook. Open that directory and create a directory called "libraries" inside that directory.
Now move the "USB\_Host\_Shield\_20" directory to the "libraries" directory.
The final structure should look like this:
* Arduino/
* libraries/
* USB\_Host\_Shield\_20/
Now quit the Arduino IDE and reopen it.
Now you should be able to go open all the examples codes by navigating to "File>Examples>USB\_Host\_Shield\_20" and then select the example you will like to open.

To use this library with the official [Arduino ADK](http://arduino.cc/en/Main/ArduinoBoardADK) uncomment the following line in [avrpins.h](https://github.com/felis/USB_Host_Shield_2.0/blob/master/avrpins.h):
The [BTD library](https://github.com/felis/USB_Host_Shield_2.0/blob/master/BTD.cpp) is a general purpose library for an ordinary Bluetooth dongle.
This library make it easy to add support for different Bluetooth services like a PS3 or a Wii controller or SPP which is a virtual serial port via Bluetooth.
Some different examples can be found in the [example directory](https://github.com/felis/USB_Host_Shield_2.0/tree/master/examples/Bluetooth).
The BTD library will also make it possible to use multiple services at once, the following example sketch is an example of this:
SPP stands for "Serial Port Profile" and is a Bluetooth protocol that implements a virtual comport which allows you to send data back and forth from your computer/phone to your Arduino via Bluetooth.
It has been tested successfully on Windows, Mac OS X, Linux, and Android.
Unfortunately Google broke something in Android 4.2, so it's currently not working in this version of Android.
More information can be found at these blog posts:
To implement the SPP protocol I used a Bluetooth sniffing tool called [PacketLogger](http://www.tkjelectronics.com/uploads/PacketLogger.zip) developed by Apple.
It enables me to see the Bluetooth communication between my Mac and any device.
### PS3 Library
These libraries consist of the [PS3BT](https://github.com/felis/USB_Host_Shield_2.0/blob/master/PS3BT.cpp) and [PS3USB](https://github.com/felis/USB_Host_Shield_2.0/blob/master/PS3USB.cpp). These libraries allows you to use a Dualshock 3, Navigation or a Motion controller with the USB Host Shield both via Bluetooth and USB.
In order to use your Playstation controller via Bluetooth you have to set the Bluetooth address of the dongle internally to your PS3 Controller. This can be achieved by plugging the controller in via USB and letting the library set it automatically.
__Note:__ To obtain the address you have to plug in the Bluetooth dongle before connecting the controller, or alternatively you could set it in code like so: <https://github.com/felis/USB_Host_Shield_2.0/blob/master/examples/Bluetooth/PS3BT/PS3BT.ino#L12>.
For more information about the PS3 protocol see the official wiki: <https://github.com/felis/USB_Host_Shield_2.0/wiki/PS3-Information>.
1._Richard Ibbotson_ who made this excellent guide: <http://www.circuitsathome.com/mcu/ps3-and-wiimote-game-controllers-on-the-arduino-host-shield-part>
2._Tomoyuki Tanaka_ for releasing his code for the Arduino USB Host shield connected to the wiimote: <http://www.circuitsathome.com/mcu/rc-car-controlled-by-wii-remote-on-arduino>
Also a big thanks all the people behind these sites about the Motion controller:
The library support one Xbox 360 via USB or up to four Xbox 360 controllers wirelessly by using a [Xbox 360 wireless receiver](http://blog.tkjelectronics.dk/wp-content/uploads/xbox360-wireless-receiver.jpg).
To use it via USB use the [XBOXUSB](https://github.com/felis/USB_Host_Shield_2.0/blob/master/XBOXUSB.cpp) library or to use it wirelessly use the [XBOXRECV](https://github.com/felis/USB_Host_Shield_2.0/blob/master/XBOXRECV.cpp) library.
__Note that a Wireless controller can NOT be used via USB!__
Examples code can be found in the [examples directory](https://github.com/felis/USB_Host_Shield_2.0/tree/master/examples/Xbox).
The [Wii](https://github.com/felis/USB_Host_Shield_2.0/blob/master/Wii.cpp) library support the Wiimote, but also the Nunchuch and Motion Plus extensions via Bluetooth. The Wii U Pro Controller is also supported via Bluetooth.
