Wii Nunchuk Arduino Controlled Model Train

Wii Nunchuk Controlled Model Train

Using an Arduino microcontroller, an Adafruit motor shield, and a Wii Nunchuk, you can create a intuitive, programmable, model train controller to run your layout.  Amaze your friends.  Entertain your kids.  Not quite DC, not quite DCC.  You’re headed for the hacker lands of PWM (pulse-width modulation).

Why do this?
 – Pulse-width modulation allows smooth operation at slow speeds.
 – Set realistic rates of acceleration and braking.
 – Set maximum speed to avoid derailments.
 – Program operational responses to meet your operating style.
 – Control train based on sensors, auto reversing, whatever.
 – Because you can, and it is cool.

There seems to be a lot of interest from the model train community in arduino projects to control various aspects of the trains, lights, and other infrastructure. It’s pretty interesting. There’s a lot you could do using sensors of all kinds to logic your trains around. We’ll be posting a lot more model train arduino projects to be sure.
