But if you don't know anything about programming or the Arduino I suggest you start with something simpler.
At the very least break your proposed project into a series of small steps - such as getting an LED to light when you press a button, getting a stepper motor to move, etc.
Don't buy a stepper motor until you understand about stepper motor driver boards.
i soldered a l297+6203 driver combo for the stepper and used simple switches to provie enable, cw/ccw steps etc. works fine.
the problem is im on time pressure and currently working on the drive belt engine and assemplage things.
the display/remote control and coding is the the next and final step. well, i dont have much experience in that but i can code c and so far it worked all well.
i asked because in case it would be a unsuitable solution with arduino you guys could tell me fast. if i resreach the pro and cons on my own, wheter arduino is a good solution, id lose a few days i cant efford right now.
