Motors, gear boxes and pulleys, OH MY!
We are making a time lapse dolley with an arduino. We need to move a 5 lb camera across a metal frame smoothly to produce a great shot. How can we do this?

How would I program this on the arduino? Any ideas for the actual coding?

You need something to SET the speed, and the arduino to interpret that and generate the pulses. Are you intending to power the trolley with a powered wheel, or a belt ?

What power have you got ?

Its undecided so far but it has to be portable. Therefore, we were thinking battery powered

How "slowly "do you want ?

the dolly works by a motor pulley system moving a camera back and forth on a track thats approximately one yard long. We need to be able to control it to the second with a vary broad range. For example the camera may need to move across the track in 30 seconds or it could need to move across the track in three hours. we have played around with the idea of a step motor but I don't know if it can give us enough control.

A MICROstepped stepper motor would be ideal.

do you know of any good sites to find one of these?

You need a driver - take a look at EBay, and then an Arduino to generate a pulse at an appropriate rate.

will this driver work http://www.ecrater.com/p/12583801/cnc-stepper-motor-driver-2m542?gps=1

Yes that's a very popular motor driver. You can try hunting around for a cheaper supplier, but that's not bad.

have you seen anything under $50?

Try this

will it connect to any step motor or do we need a specific kind

Its big enough, and asjustable enough to handle most motors you are likely to use.

Look at this user's ibles. The camera sled build may be what you need. Good luck.\ https://www.instructables.com/member/ritwika/?show=INSTRUCTABLES
