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;

Getting Started With Stepper Motor 28BYJ-48 © LGPL

This project is an easy introduction to stepper motors and aims to introduce null-level beginners to stepper motors and their respective drivers.

This project used 28byj-48 stepper motor and UNL-2003 stepper motor driver.

This project is based on the arduino UNO microprocessor.

Schematic of circuit

Follow the schematic given above. The connections are:

Stepper Motor :

Usually the female header pins of the motor are grouped and connected to the corresponding port on the uln-2003 but there can be exceptions, follow the diagram above. (view enlarged, it will help a lot!)

Arduino and Driver:

Any digital pins of your choice can be connected to the driver, starting from left for Coil A, B, C, D There are pins for E, F and G too, but we will not be using those for this project.

Connect the + port to the 5v port of the arduino, (if you wish you can also connect to the 3.3v) and the - port to the GND port of the arduino. (There are multiple GND ports, select any one.)

How the Stepper motor works

The stepper motor works by applying pulses of current respectively to each of the coils of the motor which each move the stepper motor one small step. Using this sequence repeatedly we generate movement which can be monitored to incredible levels of accuracy without PWM outputs.

Here we use the eight-phase model which energizes each coil respectively sometimes two at once. There is no need for PWM outputs here as the pulses are digital 1 or 0.

The order in which we apply the power affects the direction of the motor. If we apply power sequentially from A to D the motor turns clockwise while if we apply power sequentially from D to A the motor turns anti-clockwise.

Code

This segment defines the pins connected to each coil.

We are using 512 steps per revolution for this stepper motor.

Change this number to whatever your one is of.

This segment initializes each pin as output pin.

This segment does all the actual work. The onestep function energizes each coil in turn to produce movement. The delays in between determine the speed of onestep.

This segment will turn the motor one full turn (clockwise).

Stepper Motor (5V)

Description

This is a great first stepper motor, good for small projects and experimenting with steppers. This uni-polar motor has a built in mounting plate with two mounting holes. There are only 32 step (11.25 degree) per revolution, and inside is a 1/16 reduction gear set. (Actually its 1/16.032 but for most purposes 1/16 is a good enough approximation) What this means is that there are really 32*16.032 steps per revolution = 513 steps! The shaft is flattened so its easy to attach stuff to it with a set-screw. A perfect first stepper motor and works well with the Motor Shield for Arduino.

Maxim and Roman seemed to be ashamed of each other, and did not undress. They swam briefly, and soon returned to the tent. Shuffling in front of each other how to be and what to do next, they did not dare for a long time who would be. The first to take off the wet swimming trunks. - Max, where are you going to sleep.

Ignoring them, Ksenia went to the boss and, having lied to her about the wedding of her nephew in a distant village, asked for a vacation until. The end of the week. The boss understood everything perfectly, but allowed the vacation and even wrote out a bonus, saying: Then you will work.

Are you sure the pain is due to constipation?" as you say, it can't be otherwise.
