I'm just blogging it - the project was made by Tomoyuki Tanaka. http://www.circuitsathome.com/mcu/rc-car-controlled-by-wii-remote-on-arduino . A little video showing code capabilities and link to code posted to github.
Very nice project. I like the shift feature. Have any vids of it in action?
Wow, that's brilliant!
Is that your blog? I found the rotary encoder entry very useful yesterday, thank you.
