ok hardware is arduino uno, im looking at the stepper.h include and since being fairly new to arduino was hoping someone could answer some questions.
the pins with the designated sine wave symbol are the ones which can be used for PWM? Is that correct?
If i use the stepper(100,5,6) shown in this web pages the pulse stream would come out of pins 5 and 6, but which would be positive and which negative or does it not matter?
if i supply the arduino with 5v then the pulse stream would be 0 to 5, would that be correct?
The set speed function of the stepper module, i take it this controls the freq of the pulses, the faster the pulses the faster the speed. Am i understanding that correctly?
What i am looking to do is inside this one machine i am working on is a Warner Electric Slo-Syn stepper, it is an older drive and i know that 20 pulses = 1 inch or travel and i want to use the arduino to control this stepper rather than the old archaic thing that is in the machine now. So I am trying to wrap my head around how the arduino works so i might be able to use it.
I would also like to see if i can put an encoder signal into the arduino as it is without any additional shields and then have the arduino compute the speed based on this encoder and use that to control this stepper. But first i have to understand the stepper module.
Of course please feel free to comment on any of these.
Thanks for any and all input you can provide.
