Is there a way to get a variable current out put,

with a constant voltage?

Say 0 to 1 amp, with a constant 5 V.

Thanks.

Output from what? And controlled how?

Yes, it’s possible, but your question couldn’t be more vaguely worded.

The technical term for the circuit you describe is "power supply." Google that.
