Stepper motor code request

Projects Programming
1

Can someone please write me a code for my stepper motor with arduino uno ( Big Please )
Nema 23 with Tb 6560 driver
All i need the stepper to do is the following

  • Push button to start
  • Stepper motor 1 rotation clockwise
  • Delay for 2 seconds
  • Stepper motor 1 rotation Anticlockswise
  • End of circuit

Then if i want to repeat the process just push the start button again

You need to post this in the programmer for hire section.
I will quote $250USD per hour with a 3 month minimum and 1 month in advance plus all expenses.

You're not for real are you?

BTW:

Consider about 50% in taxes plus expenses.

I am, why? I last worked for money in 2000 and was paid $125. The rates have easily doubled in the last 25 years. Entry rate at Facebook or Google is $150,000 to $191,000 and a Principal Engineer (which sounds like my Staff level) can earn between $500,000 and $750,000. Now that I looked it up I see I am quoting too low, I need to change it to $400 an hour.

Meanwhile, in Freetown...

Just for fun, I tried AI (DeepSeek). I copied your whole post and used it as a prompt.

// Stepper Motor Control with NEMA 23 and TB6560
// Button press triggers 1 clockwise rotation, 2s delay, then 1 counter-clockwise rotation

// Define pins
const int dirPin = 5;     // Direction pin
const int stepPin = 2;    // Step pin
const int enablePin = 8;  // Enable pin (optional)

const int buttonPin = A2;  // Push button pin

// Stepper motor settings
const int stepsPerRevolution = 200;  // Change this if your motor has different steps/rev
const int pulseWidthMicros = 20;     // Pulse width in microseconds
const int rpm = 60;                  // Speed in RPM

// Calculate delay between steps in microseconds
const int stepDelay = 60000000 / (stepsPerRevolution * rpm);

// Variables
bool motorRunning = false;
bool lastButtonState = HIGH;  // Assuming pull-up resistor is used

void setup()
{
  // Set pin modes
  pinMode(dirPin, OUTPUT);
  pinMode(stepPin, OUTPUT);
  pinMode(enablePin, OUTPUT);
  pinMode(buttonPin, INPUT_PULLUP);  // Enable internal pull-up resistor

  // Disable motor initially (if enable pin is used)
  digitalWrite(enablePin, HIGH);  // HIGH typically disables the driver
}

void loop()
{
  // Read button state
  bool currentButtonState = digitalRead(buttonPin);

  // Check for button press (LOW because of pull-up)
  if (currentButtonState == LOW && lastButtonState == HIGH && !motorRunning)
  {
    // Start the motor sequence
    motorRunning = true;

    // Enable motor (if enable pin is used)
    digitalWrite(enablePin, LOW);

    // Rotate clockwise
    digitalWrite(dirPin, HIGH);  // Set direction (may need to reverse depending on your setup)
    rotateMotor(stepsPerRevolution);

    // Delay for 2 seconds
    delay(2000);

    // Rotate counter-clockwise
    digitalWrite(dirPin, LOW);  // Reverse direction
    rotateMotor(stepsPerRevolution);

    // Disable motor (if enable pin is used)
    digitalWrite(enablePin, HIGH);

    motorRunning = false;
  }

  // Update last button state
  lastButtonState = currentButtonState;
}

// Function to rotate the motor a specific number of steps
void rotateMotor(int steps)
{
  for (int i = 0; i < steps; i++)
  {
    // Generate pulse
    digitalWrite(stepPin, HIGH);
    delayMicroseconds(pulseWidthMicros);
    digitalWrite(stepPin, LOW);
    delayMicroseconds(stepDelay - pulseWidthMicros);
  }
}

I altered the pin numbers and tested with a CNC shield and button. It appeared to work.

I think the code has a few errors, but perhaps can be used a basis.

When is your project assignment due?
