How do I wire up an arduino, keypad, display to a stepper motor?
I know the basics of how stepper motors work and I'm learning about arduino boards work. How do I connect an arduino board, number pad, and digital display to control distance a nema 23 motor travels on a geared rack? I would like to be able to enter a number on the keypad, such as 12.5, have it show up on the display and then rotate the stepper the appropriate number of steps to equal 12.5". I would assume it would require some sort of calibrate function. I'd also like to be able to use metric as an option. I want to buy some parts to get started, but there is so many different types of boards, keypads and displays, I don't know where to begin.
