I have 28BYJ-48 with ULN2003 driver Why 350ma draw when 8 steps in a row every 2 sec? Constant current. Would expect a spike every 2 sec. The Uno is about 50ma, the motor only when moving. The ULN2003 takes 300ma constantly? LED's?

Why so much current?

Look at the motor knob example.
stepper.step(-1) will do it not step(-1)
