While we’ve been told all of our lives Wiis and trains just don’t mix, they never said anything about Wii Nunchuks. One terribly abused joke later, [Ken] tipped us off about his Wii Nunchuk controlled train set.

By utilizing Digital Command Control (think pulse-width modulation) with an Arduino, he is able to have full control over the trains direction and speed. The other part of the equation is a Wii Nunchuk and adapter. The setup should be pretty self explanatory, but there is an Instructable for those that need more help.
