> 3 dayThese stepper motors are small and perfect for a small-scale application. They are not as precise as a NEMA stepper but perfect for the price. I am using them to control a clock.

> 3 dayOne of the motors was packed that had come apart during manufacture. Did not disassemble as a result of handling or shipping. Tested one of the complete motors on arrival and it worked. Have not tested the other 3 yet. Have experienced this with other Chinese products bought thru Amazon. Hit and miss with regard to quality, but they are cheap.

> 3 dayDelightful little motors. Operation is a simple walk: 1 foot down, 2 feet down, and so on like: | In 1 2 3 4 / In 1 2 3 4 | In 1 2 3 4 / In 1 2 3 4 | In 1 2 3 4 / In 1 2 3 4 | In 1 2 3 4 / In 1 2 3 4 Where a foot on a pin is a high voltage on that pin; its requires a bit more of the cpu than a direction_pin, step_pin setup, but I like the more direct understanding of the phase. Operation is very smooth with the 64x gear reduction even before trying microstepping. Planning to use this to motorize the stage of my labs microscope so we can automatically optimize alignment between its laser vibrometer and reflective targets.
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;
}
}
