how to bluetooth controlled dc motor for roller coaster train

Hi all,

I'm gonna build a 3d printed rollercoaster! The idea is that the train rides on the track based on an arduino nano, with smartphone control through bluetooth. The problem is that I'm very new to arduino, I found some tutorials from a arduino uno, but the train must be so compact as possible! Can someone help me out? It only has to have 1 dc motor beacuse the only way is forward and no steering because it follows the track.

Thanks, Sam

You can normally transfer a Uno project to a Nano with no change. Same code, same pin numbers etc.

Give that a try and if it doesn't do quite what you want post again with some more detailed questions.
