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.

The demo code is at GitHub: https://github.com/OLIMEX/DUINO/tree/master/AVR/WII-NUNCHUCK

FRIDAY FREE BOARD QUIZ ISSUE #28 IS MOD-RGB

MOD-RGB is our new 3 channel RGB LED controller. Each channel can control 12V 5A LEDs so it’s suitable to control high power LEDs and RGB LED stripes.

MOD-RGB directly connects to UEXT on A13-OLinuXino, iMX233-OLinuXino, OLIMEXINO-328 Ardino like, DUINOMITE(-MINI-MEGA-eMEGA), PINGUINO, OLIMEXINO-STM32(MAPLE) and we have demo codes for all these boards. With the help of RPI-UEXT it can be connected to Raspberry Pi also or Stellaris launchpad via STELLARIS-UEXT.

On top of I2C RGB control you can use MOD-RGB as Disco Light controller when you feed Audio singal to the audio connector the R, G and B channel will blink with the low-mid-high frequencies beat.

There is provision MOD-RGB to become DMX controller with MOD-RS485 connected to the UEXT connector, but the firmware is not complete to support DMX yet.

Today at 17.00 o’clock our local Bulgarian time (GMT+2) we will post on Twitter our questions.

You have one hour to reply to our tweet with the correct answer.

At 18.00 o’clock we will count the correct answers and ask random.org to generate random number in range then announce the winner and ship the board by airmail in Monday.

Good Luck!
