Bruno Cazarim I dont understand when you say there is a collector-emitter voltage wich can be enough to turn the motor on. To participate you need to register.

EN Standart Shutdown Test 2. How can this voltage Vce turn the motor on? What is the rated torque for this motor? Hi petrv I use the above technic you described. Depednign on the current, there is a collector-emitter voltage which gets subtracted from the ukn2003 voltage, but uln2003 dc motor on your motor data, it might still be enough to turn it on.

And when I ulnn2003 nothing to pin 1, the motor turns off. You will still need an Arduino or controller to output the correct control sequence to drive the stepper in correct direction uln2003 dc motor speed.

to drive dc motor using uln2003

Anyone have a clue on that? The image attached shows the setup in case I haven’t been clear. The chip’s board has LEDs and resistors on uln2003 dc motor of pins 1 – vc, but I don’t believe they’re in series and thus my guess is they can be left off.
