Hey everyone!
I'm looking to use a stepper motor and a push button to spin from a low rpm and gradually spin faster to its maximum within 15 - 20 seconds, my question is if this is possible? If so I need help writing code for it.
It is definitely possible, sorry but I'm not good with coding. 
But yea, definitely possible
Put stepper in the search box of the Playground
Have a look at stepper motor basics and at the AccelStepper library.
