I would like to control a current source of 120A with a pot and stepper, how can i precisely vary the pot , is there any need for any memory device to save the postion ?

He said he is using a PC, not a PIC. He is planning a system like this:i will give this value to pic adc and then.....
You're wrong. He wants to use the stepper motor to turn the pot. The pot is to control the current source.if i m right then rohit wat to control a stepper with pot... [snip nonsense]
There is no PIC! Please read the question before trying to give an answer.and pot can be read using pic and pic then..........
You and Zia have fun then. You want to make a 120A current source and you think your biggest problem is how to control a stepper motor?! Why do you even think you need a stepper motor?Zia is correct....
The bottom one says 0.5A? Is your one 120A?
And what are you trying to adjust? The voltage setting on it? Because normally when people say "current source" they mean a
"constant current even if the load resistance is varying". Basically, more information/clarification is needed.
