Accelerometer @WiiChuck

As you’re probably well aware, the wiimote and nunchuck have a vast array of sensors built into them. Instead of buying pre-assembled breakout board for $35, or attempting to solder a tiny surface mount accelerometer, learn to exploit the features of the Wii Nunchuck and have a fully assembled accelerometer, joystick, and pushbuttons for just $12.50 shipped (on ebay). Why use the nunchuck insead of the actual WiiMote? 1. The Nunchuck communicates through 6 bits of data. 2. If you don’t already have it, download the Arduino software (free). 3. By using the serial monitor of your Arudino software (or other serial monitoring software), you’ll see the above output. 4. Watching numbers steam in (step 3 image) is fine and dandy, but sometimes you just need something more to create a truly new perspective. Now that you’ve learned how to read data from a nunchuck as well as data visualization, go make something awesome and don’t forget to subscribe to HacknMod for more fantastic posts.

“WiiChuck” Wii Nunchuck Adapter Available Want to hook up a Wii Nunchuck to an Arduino but don’t want to cut up the cord on your Nunchuck? Yeah me too. So I made some of these: It’s a small PCB that adapts the Wii Nunchuck connector to standard 4-pin header. I call it the “wiichuck adapter”. It plugs directly into the Arduino, no wiring necessary. Available from the following wonderful shops: - FunGizmos.com. One of the coolest things about the Wii (to me) is that the expansion port on the bottom of the Wii remote is an I2C serial connection. This “wiichuck adapter” let’s you play with the Wii Nunchuck and other Wii remote peripherals without needing you to cut cables. This is what it looks like plugged into the Nunchuck by itself. Nunchuck and Other I2C Devices (like BlinkM) You can use other I2C devices at the same time as the Nunchuck. And then you can plug in a BlinkM right on top. Software It is based off the original research done by Chad Philips of Windmeadow Labs. Nunchuck Information Getting One / How to Order
