Hi. Planning on doing some stepper motor control. Need to control speed of the stepper motor, via a pot. Also want to control the direction of the motor, but that only needs to be done once, in code.
I have an arduino nano already.
Planning on ordering this:
and
What value pot should I get?
Would I need anything else? (hardware wise).
Thanks a lot 
10k-50k linear.
Make sure that your stepper driver can handle current driven motors and adjust its current limiter to the nominal motor current. Or choose a voltage driven stepper...
Thanks.
i'm sorry, but I don't know if the stepper i linked to, can handle current driven motors. I don't even know where it states, if it can do that. (sorry fo rmy noob-ness).

This is the spec for the stepper driver:
Integrated MOSFETs to drive RMS motor current to 1.2A
Configuration via seven pins on the driver IC
No required intervention by host CPU
Up to 256 micro-steps per full step to maximize rotational precision
And these are the motor specs:

This is a Bipolar motor.
Specifications:
Step Angle (degrees) : 1.8
2-Phase (4 wires)
Rated Voltage: 3.6V
Rated Current: 1.2A/Phase
5mm Diameter Drive Shaft
Holding Torque: 48N.cm - 4.8kg.cm
NEMA 17 form factor
Shaft Diameter: 5mm
Will that work?
Thanks a lot:)
Do you know how to set these pins?
