Stepper Motor Control using Arduino is a simple project where a Bipolar Stepper Motor is controlled using Arduino UNO. Stepper Motor is a type of brushless DC Motor that converts electrical pulses into distinct mechanical movements i.e. the shaft of a stepper motor rotates in discrete steps. When a computer controls these steps, we can get precise position and speed control. In this project, we are going to design a simple system to control a stepper motor using Arduino. Okey, let's start.

Circuit Diagram
Program
// Arduino stepper motor control code
#include <Stepper.h> // Include the header file
// change this to the number of steps on your motor
#define STEPS 32
// create an instance of the stepper class using the steps and pins
Stepper stepper(STEPS, 8, 10, 9, 11);
int val = 0;
void setup() {
Serial.begin(9600);
stepper.setSpeed(200);
}
void loop() {
if (Serial.available()>0)
{
val = Serial.parseInt();
stepper.step(val);
Serial.println(val); //for debugging
}
}
