Hello,
I'm trying to make a conveyor belt to move back and forward, the motor and electrical parts are to be concealed. I've been using the Super starter kit UNO R3 Project, and I'm concerned that the 9volt battery won't last, as it seems to drain the battery quite quick. By any chance, is there a way to have the motor run on batteries for about 9-10 hours?
Sure, but it would take a fairly beefy battery, like a 12V motorcycle starter battery, or a rechargeable pack intended for an RC race car.
Batteries are rated by capacity, either mAh (milliAmpere hours) or Ah (Ampere hours).
Approximate battery lifetime in hours = (battery capacity in mAh)/(average current draw in mA).
shoot it from above with a Tesla coil..
charge the batts wireless and look good doing it..
it's art right?? don't hide the prettiest part..

I use a 1/4 dead 14Ah e-bike battery with a USB/5vdc port to power a meter of LED for two weeks (14 days)... yeah, it weighs 4 kilograms.
How many cm backward and forward?
Thank you for your reply, I will definitely keep this in mind as an option!
I think the Tesla coil may be a little too advance for me🤣 but thank you for the suggestion!
My tutor said the same thing that I don't need to hide the mechanics as it's part of the art!
The full length it has to roughly travel is 70cm but I would change the speed for it to travel very slowly (role per minute 4) as I was thinking this may prolong the battery life as well.
I think a 4kg bike battery may be a little to heavy. However, I may be able to find a small battery-pack for a mobile phone. But thank you for your suggestion!
Thank you for your suggestion but I think I'm going to have to find two small battery-packs and change them half way through the day. I think I'm going to have to do a few trials!
Is this over rollers or over a flat surface?
What is the weight to be moved?
I'm planning on it being a flat surface, pvp pipe at either end with the motor attached to one and maybe couple in the middle for support if needed. The cover will be leather or a elastic fitness band and I will have a light on top, it will either be a lightweight LED that I wire up or a small key chain torch.
Hi,
Will you be using limit switches the make the belt change direction?
or
What is you project using to decide when to reverse the belt, time or a sensor at each end of the travel distance.
or
will the belt be moving more that 1/2 a turn between changes?
Can you please post link to specs/data on motors?
Thanks.. Tom.. 
Approx. 70cm over 4 minutes... if I have read this right...

@bigmuffin101
Is there a plan for the "70cm" of platform (and items) that move "out of scene" and will be replacing the empty 70cm at the other end? Or will this be a scene, centered, with 70cm of empty space?
Hello,
we using the code from Arduino UNO R3 23 stepper tutorial, I'm still new to this so I'm trying to make it simple. We're doing 1/2 turns for it to be going back and forward, the light on top will never go underneath.
Hello,
the piece will be centred around the conveyor belt, there will be light that will move back and forward on the top half.
For the platform, consider a rigid "stage" on any type of roller that is 70+mm wider than the viewing area (35mm on each side). Drive the whole stage back and forth with a light duty motor (Nema17 is popular with Arduino projects) which rotates a linear screw shaft connected to the stage.
