Stepper Motor - Arduino

I used a LM2008A transistor array to drive this motor. Power supply was an PC power supply 5v (red). A 1 ohm resistor was in place between the Vcc and the shared (Common) stepper wire...

Stepping Sequence was:
Black, Red, Blue, Green


This is a Applied Motion Products Stepper Motor:


Part Number: 44A50177
2.3 Volts
2.3 Amps
60oz Torque

//This was a small test to see if I could get this motors stepping
//The current is around 500ma so stopping these motors is VERY easy however
//I just wanted to see if they would step.

int coilPin11 = 11; //These are the pins connected to the output of the
int coilPin10 = 10;//lm2008a in the order of how your motor steps
int coilPin09 = 9; //
int coilPin06 = 6; //
int speed = 2 //This sets the delay between steps which is basically your Speed.

void setup()
{
pinMode(coilPin11, OUTPUT);
pinMode(coilPin10, OUTPUT);
pinMode(coilPin09, OUTPUT);
pinMode(coilPin06, OUTPUT);
}

void loop()
{
digitalWrite(coilPin06, HIGH); //sets this coil on
delay(speed);//speed
digitalWrite(coilPin06, LOW); //sets that coil to off

digitalWrite(coilPin09, HIGH); //etc
delay(speed);
digitalWrite(coilPin09, LOW); digitalWrite(coilPin10, HIGH);
delay(speed);
digitalWrite(coilPin10, LOW); digitalWrite(coilPin11, HIGH);
delay(speed);
digitalWrite(coilPin11, LOW);

}

I mis-spoke in the video. The yellow wire puts out about 4.4Amps the red wire (5v) puts out around 1.2Amps.  Sorry.

Why are you using a 1ohm resistor? I'm kinda new with this so please excuse my stupidity

Also is there a reason for using that other chip instead of only the arduino? What does it do?

@ebutuou123: anything is anything.

[ebutuou123]

can you use any stepper motors in an arduino? Or only certain ones?

Hi...tnx for share...I working in a joule thief charger that uses one big transistor, the Q is this transistor array chips like ULN2803A can be conected in series? It can be conected like a standart transistor using just 3 legs of the chip CBE or need special conection? can I make a darlinton pair with 2 2n3904?
