Instructions

Objective:

Learn how to control a stepper motor using Arduino to achieve precise rotational movements step by step.

Steps to Perform:

Click "Start Simulation" to power up the Arduino circuit
The stepper motor will begin rotating continuously
Motor completes one full revolution (200 steps) per cycle
Speed is set to 90 RPM (Rotations Per Minute)
The motor repeats the rotation pattern in loop()

Key Concepts:

Stepper Motor: Motor that rotates in discrete steps for precise positioning
Stepper Library: Arduino library for controlling stepper motors
Steps Per Revolution: 200 steps = one complete 360° rotation
Pin Configuration: Uses pins 8, 9, 10, 11 for motor driver control
setSpeed(): Sets rotation speed in RPM (90 rotations/minute)
step(): Moves motor by specified number of steps (positive = clockwise)
Precision Control: Each step provides ~1.8° rotation (360°/200)

Arduino Code - main.ino

            #include <Stepper.h>

const int stepsPerRevolution = 200;  
Stepper myStepper(stepsPerRevolution, 8, 9, 10, 11);

void setup() {

}

void loop() {
    myStepper.setSpeed(90);
    // step 1/100 of a revolution:
    myStepper.step(stepsPerRevolution);
 
}
