Simple Current Limiting Circuit. Which gets its base bias from a 5 k variable resistor. When the input is low q1 is off and no current flows through the load.
As before when the input to the base resistor is 5v q1 turns on and current flows through the load. Simple current limit circuit. Read carefully step.
I choose 1k ohm but any potentiometer will work too.

With the values shown the output cut off current or current limit can be set from 5 ma to 500 ma. I choose 1k ohm but any potentiometer will work too.
