The "Leonardo Wii Nunchuck Mouse"

 The Nintendo Wi Nunchuck is an interesting form of user input that can be harnessed quite easily for other projects without too much effort. This is thanks to the fact that the sensors inside communicate via the I2C bus - perfect for interfacing with an Arduino. One example of this has been created by the people at "Fork Robotics",  who have created a mouse emulator using a Wiichuck and an Arduino Leonardo. 

As the Leonardo (and compatible boards such as our LeoStick) can easily emulate a mouse - and the Nunchuck can be read via USB - a mouse with some interesting physical movement requirements can be created. 

To find out more and review the Arduino sketch, visit the project page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

To get started with your own embedded-Arduino and USB emulation projects - look no further than the Freetronics LeoStick. Apart from being one of the smallest Arduino-compatibles on the market with USB, it also has an onboard RGB LED and piezo for sound and knock detection:
