> 3 dayI’m new to using steppers and these are the first ones I’ve had. I got them because I have a few projects in mind that could benefit from their qualities. The packaging and everything was very nice, and getting five motors and five drivers for this price is incredible. However, they’re cheap quality as one might expect. There is a bit of slop in the gearing when stationary, but not much (maybe 2-5°). I was disappointed at the low amount of torque they had, even driven slowly with full stepping I could overpower them with my fingers on the little shaft. Still, with the appropriate output gearing, these could be plenty strong for a lot of applications.

> 3 dayAll the products I have gotten from this company have great quality and value for the price!! Motors work exactly as expected.

> 3 dayHighly likeable. These work as expected. Dont expect a great deal of pep out of these; they are geared to provide torque more so than speed. At 12v, these get quite toasty, so Id recommend using 5v.

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.

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;
}
