Hi guys, I'm a good machinist and want to build a hardware dashboard from scratch but i'm a noob at electronic. I'm thinking using a Pololu USB servo controller with rc servos. My questions are:
-Do I need to use continuous rotation servos? If yes, do they have "home position" so that they return to the same point everytime my dashboard is to be turn on and off?
-Do I really need to pass through a parrallel port from my computer then convert it to USB for a Pololu controller to work with SimX? Or can I just plug a USB Pololu card using a USB port on my pc?
