camrea slider motor project

Hi. Complete arduino newb here

Im looking to build a motor system for a camera slider I already have.

Things I would like to include is bluetooth intergration so that I am able to conect to an app on my phone to be able to contol speed and duration of the motor. I dont even know where to start with this so would love some help in getting this thing going.

Cheers for any help
