I'm pretty new to electronics and the Raspberry Pi. I would like make a surveillance camera from the RP for the teaching purposes, so I figured I will need the camera, and two stepper motors, to make it possible to move the camera remotely in two dimensions. I'm experienced programmer, however I lack the basic knowledge when it comes to electronics. What are important things to consider when choosing the stepper motor for a RPi project? I mean:
What to look at to be sure that the RPi will handle the stepper motor (power-wise etc.)?
Few example torque values that are "just enough" for the example jobs.
With the above information, it would be very easy for the beginners like me, to start working with motors and RP.
