I'm currently planning a project to build a 2 axis timelapse head. And I'm looking to power 2 steppers using an arduino uno and a motor shield:
I will be using 2 of these motors:
the head would turn around 360 degrees and would be able to move up and down at 180 degrees
The problem I have is that there is no program out there that will achieve what I want to do so i'd like to see if there is anyone out there that would be willing to try and code one.
What I am trying to control is the number of steps that the motor does over a period of time..
e.g if one step = 0.5 degree
and I wanted to go +180 degrees over a 3 hour period that would be 360 steps over 180 minutes.. so 2 steps per minute or 1 step over 30 seconds
if that makes sense...
