Program coding of arduino interfacing with stepper motor with LCD.

#include <Stepper.h>
#include <LiquidCrystal.h>
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);

#define STEPS 100

Stepper stepper(STEPS, 8, 9, 10, 11);

int previous = 0;
int motorSpeed = 20; // Initial motor speed

const int forwardButtonPin = 12; // Pin for the forward button
const int reverseButtonPin = 13; // Pin for the reverse button
const int stopButtonPin = 2; // Pin for the stop button

void setup() {
stepper.setSpeed(motorSpeed);
lcd.begin(16, 2);
lcd.print(“Speed:”);
lcd.setCursor(7, 0);
lcd.print(motorSpeed); // Display initial speed value
lcd.setCursor(0, 1);
lcd.print(“Status: STOP”); // Display initial status

pinMode(forwardButtonPin, INPUT_PULLUP);
pinMode(reverseButtonPin, INPUT_PULLUP);
pinMode(stopButtonPin, INPUT_PULLUP);
}

void loop() {
int val = analogRead(A0);
int numSteps = map(val, 0, 1023, 0, 200); // Adjust the range of steps as needed

// Read button states
int forwardButtonState = digitalRead(forwardButtonPin);
int reverseButtonState = digitalRead(reverseButtonPin);
int stopButtonState = digitalRead(stopButtonPin);

// Move the motor based on button presses and update status
if (forwardButtonState == LOW) {
stepper.step(numSteps);
lcd.clear();
lcd.print(“Speed:”);
lcd.setCursor(0, 1);
lcd.print(“Status:”);

lcd.setCursor(8, 1);
lcd.print(“FWD “);
}
if (reverseButtonState == LOW) {
stepper.step(-numSteps);
lcd.clear();
lcd.print(“Speed:”);
lcd.setCursor(0, 1);
lcd.print(“Status:”);
lcd.setCursor(8, 1);
lcd.print(“REV “);
}
if (stopButtonState == 0) {
stepper.step(0); // Stop the motor
lcd.clear();
lcd.print(“Speed:”);
lcd.setCursor(0, 1);
lcd.print(“Status:”);
lcd.setCursor(8, 1);
lcd.print(“STOP”);
}

// Display the current speed on the LCD
lcd.setCursor(7, 0);
lcd.print(” “); // Clear previous value
lcd.setCursor(7, 0);
lcd.print(motorSpeed);

// You can add a delay here if needed
delay(100);
