Arduino UNO Code

#include <Stepper.h>
#include <Servo.h>

#define OUTPUT1   4
#define OUTPUT2   5
#define OUTPUT3   6
#define OUTPUT4   7

Servo servo;
const int stepsPerRotation = 2048; // 
Stepper myStepper(stepsPerRotation, OUTPUT1, OUTPUT3, OUTPUT2, OUTPUT4);  

void setup() {
  servo.attach(8);
  servo.write(90);
  myStepper.setSpeed(15); // RPM (Round Per Minute)
}

void loop() {
  myStepper.step(stepsPerRotation);
  delay(500);

  delay(500);
}

This code initializes a stepper motor and a servo motor. The stepper motor is controlled to rotate in both directions, while the servo motor moves between 0, 90, and 180 degrees. The setup() function initializes the servo motor to 90 degrees and sets the speed of the stepper motor. The loop() function continuously rotates the stepper motor and moves the servo motor between specified angles with delays in between.
