Motors, gear boxes and pulleys, OH MY! Answered

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 ?

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

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.

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

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

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