> 3 dayI would give a more thorough review as I just received it and will probably not be able to utilize the stepper motors in a project until later in the year.

> 3 dayYeah, bought these... not really looking into the details. They are VERY SLOW. Too slow for my application. I can stop the shaft with my fingers, so no real torque either.

Greater than one weekJust did a breadboard with the sample code from this page and tried all of the steppers in it. Three of the five only turn in one direction and simply shudder when trying to turn in the other direction. Two of them work in both directions as expected. After fooling around with these on my Raspberry Pi Zero W2, I found the real problem is the 800 microsecond delay in the code, it is too small - bump it up to 900 and all five of the steppers work fine.

> 3 dayGreat little motors and nice controller board. The gear head fits snugly into Lego gears (you might need to trim gear mounting a little). Not a lot of torque, but fantastic for the price. I ended up ordering 4 sets of these for various projects. Took a little time to figure out the stepper sequence, but good reference on the web.

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.
- Stepper motor with a standard interface, when used directly pluggable.

- 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;
}
}
