Hello ive been working on some code to for a simple powerfeed and got most of it working only things i now run in to is that when no switch is made the enable should be made high ie 5v at the moment it goes low to ground easily fixed in the wiring but is it also possible in the code ?
Second when a switch is selected and my 10k pot is all the way to 0 it still turns and i want it to then be still/stopped is there a way to fix that?
or would it be better to use ContinuousStepper lib?
