But there is a few questions I need answering before I'm willing to get all the stuff I need as I don't want to waste money!
Have you bought the stepper motors yet? This stepper come with driver, is cheap and already geared down to just under 0.09 degree per step. Might make the build a lot easier.
I want to power two motors.
-I guess I will need 2 SN754410ne H-Bridge's?
-Can I run these of a single Arduino at the same time and how?
You will need to power the steppers separately as the arduino cannot supply the power needed directly.I need these motors to run slow at approximately 144 steps (180 degrees @ 0.8 degree per step) over a 3-4 hour period
- Can I go this slow with the program?
- What would I type into the requires fields? the program confuses me slightly..
The maths does not add up, 144 steps x 0.8 degree = 115.2 not 180
Your maybe better off describing it in terms of total angle of time-lapse, total number of stills (frames) & duration.
