The Neo pixel and on-off switch code.

#include <Adafruit_NeoPixel.h>

#ifdef __AVR__

  #include <avr/power.h>

#endif

Libraries: The code begins by including the necessary libraries. Adafruit_NeoPixel.h library is used for controlling the NeoPixel ring. 

#define PIN            6

#define NUMPIXELS      8

#define BUTTON_PIN     7

PIN: This defines the pin to which the NeoPixels are connected. In this case, it's pin 6.

NUMPIXELS: This specifies the number of NeoPixels in the ring. Adjust it according to your setup.

BUTTON_PIN: This defines the pin to which the push button is connected. It's pin 7

Adafruit_NeoPixel pixels = Adafruit_NeoPixel(NUMPIXELS, PIN, NEO_GRB + NEO_KHZ800);

int delayval = 500;

void setup() {

  pixels.begin(); // This initializes the NeoPixel library.

  // Set button pin as input

  pinMode(BUTTON_PIN, INPUT_PULLUP);

}

The setup() function initializes the NeoPixel library using pixels.begin().

It sets the BUTTON_PIN as an input with the internal pull-up resistor enabled, indicating that the button is connected to ground when pressed.

void loop() {

  // Check if the button is pressed

  if (digitalRead(BUTTON_PIN) == LOW) {

    // Open the LEDs

    for(int i=0; i<NUMPIXELS; i++) {

      pixels.setPixelColor(i, pixels.Color(255,255,255)); // Moderately bright green color.

    }

    pixels.show(); // This sends the updated pixel color to the hardware.

  }

  else {

    // Close the LEDs

    pixels.clear(); // Turn off all LEDs

    pixels.show(); // Update NeoPixel ring

  }

}

The loop() function continuously runs and checks if the button connected to BUTTON_PIN is pressed.

If the button is pressed (logic LOW), it lights up all the NeoPixels in white.

If the button is not pressed (logic HIGH), it turns off all the NeoPixels.

The Stepper motor and pushbutton code.

#include <Stepper.h>

Libraries: The code includes the Stepper.h library, which provides functions to control a stepper motor. 

int stepsPerRevolution=100;  // stepping space

Stepper myStepper(stepsPerRevolution,2,4);

int motSpeed=100; // speed

int buttonPin = 5;

Global Variables:

stepsPerRevolution: This variable defines the number of steps required for one complete revolution of the stepper motor. In this case, it's set to 100.

motSpeed: This variable sets the speed of the stepper motor. It's set to 100 steps per second.

buttonPin: This variable specifies the pin to which the push button is connected. It's set to pin 5.

void setup() {

  // Set the push button pin as input

  pinMode(buttonPin, INPUT_PULLUP);

  // Set the speed of the stepper motor

  myStepper.setSpeed(100);

}

Setup Function:

The setup() function is called once when the Arduino starts.

It sets the buttonPin as an input with the internal pull-up resistor enabled. This configuration allows the Arduino to read the state of the push button, which is connected to ground when pressed.

The speed of the stepper motor is set using myStepper.setSpeed(motSpeed).

void loop() {

  // Read the state of the push button

  int buttonState = digitalRead(buttonPin);

  // If the button is pressed (active low), move the stepper motor

  if (buttonState == LOW) {

    // Move the stepper motor one step clockwise

    myStepper.step(500);

    delay(5); // Delay for smoother movement (adjust as needed)

  }

}

It reads the state of the push button using digitalRead(buttonPin). If the button is pressed (active low), meaning it's connected to ground, buttonState will be LOW.

When the button is pressed, the if statement checks if buttonState is LOW, indicating the button is pressed.

Inside the if block, the myStepper.step(500) function is called to move the stepper motor 500 steps clockwise. This value determines the number of steps the motor will move each time the button is pressed.

A small delay of 5 milliseconds (delay(5)) is added for smoother movement of the motor.

// When we setup the NeoPixel library, we tell it how many pixels, and which pin to use to send signals.

Hala helped my alot speacially in coding and wiring the component she make this step more easy to me.

also Mr. Wassiem share with me a video for how to wire a stepper motor also shared with me a code for Stepper.

The stepper motor on grab cad its dimensions are not same as the real one that is make the holder is small because i used the one on grab cad as a referance.

The base dimensions is bigger than the sheet so the slots were cutting.

The first coupler design was small so it wasn't able to be put on the motor shaft.

I designed a new one with bigger dimensions.

the motor is weak to hold and rotate the turntable it is function will when it dose not hold it.

I will add a speaker told the story.
