WII NUNCHUCK projects with Arduino Leonardo AVR-T32U4



WII NUNCHUCK is low cost joystick and 3 axes accelerometer combo which could be read by I2C.

We created UEXT plug-in board which allow WII-NUNCHUCK to be used with any of our development boards with UEXT connector.

Here on this video: http://www.youtube.com/watch?v=fXa6AA9Aq_o

you can see four projects made with WII-NUNCHUCK

1. Mouse – you can move the mouse pointer with Joystick and to use the two buttons as mouse buttons

2. Sound – with the 3 axes accelerometer you can change the pitch of the generated tone

3. Driving two servos with the 3-axes accelerometer

4. Drivinig RGB stripe with MOD-RGB and MOD-WII-NUNCHUCK – as AVR-T32U4 have just one UEXT port we use the UEXTx5 extender.

New Product: USB-MINI-2-USB-HOST adapter


A13 processor have two USBs, one is HIGH SPEED USB host, the other is USB-OTG.

A13-OLinuXino and A13-OLinuXino-WIFI have build in USB hub, so the USB hosts support keyboards, mouses etc HID devices.

A13-OLinuXino-MICRO have no hub, so on the USB host you can’t attach directly HID devices, only through hub.  Interesting feature is that USB-OTG supports HID devices, but to connect USB keyboard or mouse is difficult to USB mini connector, this is where USB-MINI-2-USB-HOST is used.

If you want to connect to A13-OLinuXino-MICRO keyboard you can do it with this adapter connected to the mini USB-OTG connector.
