So I am very new to the arduino platform, and I am working on a project where I am controlling multiple stepper motors. However, I am using 3 stepper motors per arduino, and two arduinos will be controlled by Xbees, whereas the other 2 will be plugged in directly to my computer. I'd like to know the most efficient way to do this, or if it's even possible at all. Does the arduino platform have an option where you can select which port to program? And does it also have an option where I can tell it which frequency to use for the XBees? I greatly appreciate any advice!
