Stop and start a stepper motor HEELLLLPPP!

Hi all,

I have been struggling with this for days. I cannot get my stepper motor to start and stop. using my IR remote. as soon as I press the motoOn = False statement everything stops permanently.

#include <Ucglib.h>
#include <DIYables_IRcontroller.h>
#include <Stepper.h>

// Define pins for SPI TFT display
#define TFT_CS     10 // Chip select pin
#define TFT_RST    9  // Reset pin
#define TFT_DC     8  // Data/Command pin

// Create an instance of the ST7735 display using Ucglib
Ucglib_ST7735_18x128x160_HWSPI ucg(TFT_DC, TFT_CS, TFT_RST);

// Define pins for Stepper Motor
#define IN1 3
#define IN2 4
#define IN3 5
#define IN4 6

// Define the number of steps per revolution for your stepper motor
const int stepsPerRevolution = 2048; // For 28BYJ-48 stepper motor

// Create an instance of the Stepper class
Stepper myStepper(stepsPerRevolution, IN1, IN3, IN2, IN4);

// Define pin for IR receiver
#define IR_RECEIVER_PIN 2 // The Arduino pin connected to IR controller

// Create an instance of the IR receiver
DIYables_IRcontroller_21 irController(IR_RECEIVER_PIN, 200); // debounce time is 200ms

// Speed variables
int speedLevels[9] = {1, 2, 3, 4, 5, 6, 7, 8, 9}; // Speed levels for buttons 1 to 9
int currentSpeedIndex = 1; // Start at a medium speed
bool motorOn = true; // Motor starts on

void setup() {
  Serial.begin(9600);

  // Initialize the TFT display
  ucg.begin(UCG_FONT_MODE_TRANSPARENT);
  ucg.clearScreen();
  
  // Display the initial message
  ucg.setFont(ucg_font_ncenR12_tr);
  ucg.setColor(255, 255, 255);
  ucg.setPrintPos(0, 15);
  ucg.print("Press KEY 0 to turn on motor!");

  // Initialize the stepper motor speed
  myStepper.setSpeed(speedLevels[currentSpeedIndex]);

  // Initialize the IR receiver
  irController.begin();
}

void loop() {
  Key21 command = irController.getKey();
  if (command != Key21::NONE) {
    switch (command) {
//      case Key21::KEY_CH_MINUS:

      case Key21::KEY_NEXT:

        break;

       case Key21::KEY_PREV:
       if (currentSpeedIndex > 0 && motorOn) currentSpeedIndex--; // Decrease speed
        // TODO: YOUR CONTROL
        break;

      case Key21::KEY_1:
      Serial.print("button1-speed1");
      if (motorOn) currentSpeedIndex = 0;
        break;

        break;
  
      case Key21::KEY_CH_MINUS:

        break;

      default:

        break;

    // Update stepper motor speed
    if (motorOn) {

    } else {
      myStepper.setSpeed(0);
      ucg.clearScreen();
      ucg.setPrintPos(0, 15);
      ucg.setColor(255, 0, 0); // Red color for motor off
      ucg.setFont(ucg_font_ncenR12_tr);
      ucg.print("Motor off");
    }
    
    delay(200); // Debounce delay
  }

  // Run the stepper motor at the current speed
  if (motorOn) {
    myStepper.step(stepsPerRevolution / 100); // Adjust steps to simulate continuous rotation
  }
}
IR Remote control my stepper motor

Please, refrain from posting different topics of the same subject. You have 44 posts. Read them, learn from them, do some work.

I did lots of homework and got to a great position with the code, check I used your advice to avoid using the delay function. I couldn't use the millis() function and as you can see it was totally unnecessary, but I am really, really stuck with this one piece. So I was hoping someone from the programming forum may be able to help.

This new topic of yours is disregarding the rules. You have another active topic with the same subject. It matters not that you did not yet figure it out. The request was to stop creating more topics on the same subject, not follow up with asking "anyone but me" to help you. Finish your work... linked above.
