this is a really, really beginner question, but I can't see where to get started. I want to buy the V-Slot™ Linear Actuator Build (Belt Driven), and just have it move all the way from one end to the other end, stopping at each end until a button is pushed, or a switch is turned. I can buy the stepper motor with the v-slot kit, but don't know what electronics I need for these simple (?) moves. I'm hoping to just have it run from a battery and do the following: 1. Push the button, the mounting platform moves all the way to the end (hits a limit switch?) and stops. 2. Push another button, and it moves all the way to the other end, and stops. Sounds dead simple I know, but I don't know what to get and how to do it. Any help definitely appreciated!
