Those don't have enough juice to power an Arduino for long, never mind a motor. They have very low total energy storage (measured in mAh, 500 mAh is common) and very low peak current. (A little googling said "Estimate 350 mA peak for 10 minutes".) If your motor needs 800 mA, you have less than half the current you need to even run the thing. It might work for a few seconds when the battery is completely fresh, but it might not. | |

Thankfully the Arduino isn't Dead (yet) so I decided to Use a 9V battery with a Voltage divider to power the driver and the motor But now when the arduino Starts driving the stepper the driver's led starts flickering instead of staying constant. And now the motor doesn't turn (see my last edit for more details) | |
