    Of the 5 ULN2003 boards, 4 had bad leds. One board had zero working leds.

    Motors work as expected. Quick delivery. Happy with this purchase.

    After I figured out how to run these, they are pretty cool. Amazing how cheap they are. My only concern is the slop, you can rotate a large enough arm freely by a few degrees without load and maybe thats how it is regarding high gearing/backlash. Anyway not complaining different needs but yeah. I think its a great deal and once figured out how to make it work, great to use for various applications. Ive used 3 out of 5 so far ha.

    The stepper motors are perfect for experimenting with multiple motors and working through your code, to make sure it works. The driver boards that arrived are different from those shown as the LEDs are reverse mounted and smaller. But the board performs properly. For the price, the value is spot on. Elegoo delivered for a very reasonable price. Very Satisfied.

    They rotate a little bit slowly with the default stepper library from arduino, but accel stepper library is quite jazzy.

    These motors actually feel pretty good and are relatively easy to control. Theyll even take a 3.3V control input, which makes them great for STM32 and STM8. Their step size is really fine due to their gearing. However, they do have quite a bit of backlash, which hinders their repeatability somewhat. Nevertheless, theyll be good for learning how to control stepper motors and for places where accuracy isnt too critical. They arent particularly strong at 5V and tend to stall out under light to medium loads. Despite their voltage rating, they run perfectly fine at 9V (Do so at your own risk!) and are definitely more powerful, but get much warmer, as to be expected. They are a bit noisy due to the gearing, but are definitely on the quiet side when it comes to steppers. Overall, theyre a good starting point for stepper motor control, and perhaps even small robotics applications. And for the price, theyre pretty good at what they do. Plus, the plastic box they include is handy for storing the motors, or other projects.

BYJ48 STEPPER MOTOR

Stepper Motor is a type of electromagnetic device which moves in discrete steps. This has several coils, the center shaft has a series of magnets mounted on it, and the coils surrounding the shaft are alternately given current or not, creating magnetic fields which repulse or attract the magnets on the shaft, causing the motor to rotate.
This Unipolar Stepper Motor 28-BYJ48 is provided with five wires and four coils. The center connections of the coils are tied together and usually used as the power connection. They are named unipolar steppers because power always comes in on this one pole.

Specification

- A, B, C, D four-phase LED indicates the status of the stepper motor work.

- Temperature Rise: < 40K(120Hz)

Programm Code Example

The Arduino IDE support a library for stepper motor, after connect motor with microcontroller you can upload the sketch on to the microcontroller. The following is the code of an example program, it can be modified according to your needs:

#define IN1 8
#define IN2 9
#define IN3 10
#define IN4 11
int Steps = 0;
boolean Direction = true;
void setup() {
Serial.begin(9600);
pinMode(IN1, OUTPUT);
pinMode(IN2, OUTPUT);
pinMode(IN3, OUTPUT);
pinMode(IN4, OUTPUT);
}
void loop() {
for(int i=0; i<4096; i++){
stepper(1);
delayMicroseconds(800);
}
Direction = !Direction;
}

void stepper(int xw) {
for (int x = 0; x < xw; x++) {
switch (Steps) {
case 0:
digitalWrite(IN1, LOW);
digitalWrite(IN2, LOW);
digitalWrite(IN3, LOW);
digitalWrite(IN4, HIGH);
break;
case 1:
digitalWrite(IN1, LOW);
digitalWrite(IN2, LOW);
digitalWrite(IN3, HIGH);
digitalWrite(IN4, HIGH);
break;
case 2:
digitalWrite(IN1, LOW);
digitalWrite(IN2, LOW);
digitalWrite(IN3, HIGH);
digitalWrite(IN4, LOW);
break;
case 3:
digitalWrite(IN1, LOW);
digitalWrite(IN2, HIGH);
digitalWrite(IN3, HIGH);
digitalWrite(IN4, LOW);
break;
case 4:
digitalWrite(IN1, LOW);
digitalWrite(IN2, HIGH);
digitalWrite(IN3, LOW);
digitalWrite(IN4, LOW);
break;
case 5:
digitalWrite(IN1, HIGH);
digitalWrite(IN2, HIGH);
digitalWrite(IN3, LOW);
digitalWrite(IN4, LOW);
break;
case 6:
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
digitalWrite(IN3, LOW);
digitalWrite(IN4, LOW);
break;
case 7:
digitalWrite(IN1, HIGH);
digitalWrite(IN2, LOW);
digitalWrite(IN3, LOW);
digitalWrite(IN4, HIGH);
break;
default:
digitalWrite(IN1, LOW);
digitalWrite(IN2, LOW);
digitalWrite(IN3, LOW);
digitalWrite(IN4, LOW);
break;
}
SetDirection();
}
}
void SetDirection() {
if (Direction == 1) {
Steps++;
}
if (Direction == 0) {
Steps--;
}
if (Steps > 7) {
Steps = 0;
}
if (Steps < 0) {
Steps = 7;
}
}
