Arduino + Wii Nunchuck = Good fun
As an update to my last post about the microcontroller known as the Arduino, here’s a very interesting video I found on youtube, as well as it’s documentation.
Basically what they are doing is reading the sensor (human input) data from the Wii Nunchuck, which (thank you Nintendo) uses a standard i2c interface. Once they have that data anything can be done with it. In this case, 2 servos are controlled creating a pan tilt mechanism that mimics the motion of the nunchuck. Clicking either link at the end of this post will explain more fully.
Neat thing about the nunchuck- It has a 3 axis accelerometer, 2 buttons, and a 2-way digital DPAD/thumbstick. Not to mention it’s sleek look and ergonomic design. Most hacking diy types would have to pay 80 bucks for a product of that caliber. But, then again, we are the hacking type. Instead of paying 80 dollars or more for all of the components and building it ourselves, we embraced a different idea. Why remake the wheel? For only 20 dollars, the nunchuck is the perfect add on to any project requiring some human input. If only I had known that before I bought my accelerometer.
A spare nunchuck has been pulled out of my junk pile. It was ruined when a small dog chewed through the insulation on the cable. I’ve got some ideas bouncing around in my head. It should be interesting to see where they go.
