driving stepper motor ULN2003 with motor shield

is there a way to drive a uln2003 faster with a motor shield. I've used motor test for the motor shield and the motor only goes really slow. I need more speed is there a code to get it to go fast?

What motor are you using?
Show us a schematic of your circuit.
Show us your schetch.
Put your sketch between the code tags [code][/code]

If this is a stepping motor, they aren't fast.

.

#include <AccelStepper.h>
#include <AFMotor.h>

// two stepper motors one on each port
AF_Stepper motor1(200, 1);
AF_Stepper motor2(200, 2);

// you can change these to DOUBLE or INTERLEAVE or MICROSTEP!
// wrappers for the first motor!
void forwardstep1() {
motor1.onestep(FORWARD, SINGLE);
}
void backwardstep1() {
motor1.onestep(BACKWARD, SINGLE);
}
// wrappers for the second motor!
void forwardstep2() {
motor2.onestep(FORWARD, SINGLE);
}
void backwardstep2() {
motor2.onestep(BACKWARD, SINGLE);
}

// Motor shield has two motor ports, now we’ll wrap them in an AccelStepper object
AccelStepper stepper1(forwardstep1, backwardstep1);
AccelStepper stepper2(forwardstep2, backwardstep2);

void setup()
{
stepper1.setMaxSpeed(200.0);
stepper1.setAcceleration(100.0);
stepper1.moveTo(24);

stepper2.setMaxSpeed(300.0);
stepper2.setAcceleration(100.0);
stepper2.moveTo(1000000);

}

void loop()
{
// Change direction at the limits
if (stepper1.distanceToGo() == 0)
stepper1.moveTo(-stepper1.currentPosition());
stepper1.run();
stepper2.run();
}

the motors I’m using is

Elegoo 5 sets 28BYJ-48 ULN2003 5V Stepper Motor + ULN2003 Driver Board for Arduino on amazon.

What speed do you need out of that stepping motor?

.

A ULN2003 is a driver. You don't get any benefit from driving one driver with another.

...R

Do those motors come with internal gear?
I think I saw some threads around here about these motors.

If so, you need to send more steps/sec to the ULN2003 shield (and don’t cascade two ULN2003, as @Robin2 said before). Test some other values in those lines:

AF_Stepper motor1(200, 1);
AF_Stepper motor2(200, 2);

and

stepper1.setMaxSpeed(200.0);
    stepper1.setAcceleration(100.0);
    stepper1.moveTo(24);
    
    stepper2.setMaxSpeed(300.0);
    stepper2.setAcceleration(100.0);
    stepper2.moveTo(1000000);

Start with doubling the speed values, put “setAcceleration” to 1000 for both steppers (and leave that value) and if the speed increases, go on with higher speed values until the motors stall, then you got slightly over the max speed.

But, if you have the motors with 64:1 gears inside, don’t expect too much.
