Your code is not readable. Please use EDIT - copy for forum - and then paste into your post.

Before that press CTRL - T .
The error message tells you in which line you have errors.

You wrote in the German forum - I asked the moderation to move it to a suitable English group.

Does it fit that way now?

I don't speak english - the text is translated with deepl.
If you format the code with CTRL-T, you will see your errors almost by yourself.

I use a customized formatting and with me it looks like this after CTRL-T:

#include <AccelStepper.h>


#define motorPin1  8                // IN1 pin on the ULN2003A driver
#define motorPin2  9                // IN2 pin on the ULN2003A driver

#define motorPin4  11               // IN4 pin on the ULN2003A driver

int stepsPerRevolution = 64;        // steps per revolution
float degreePerRevolution = 5.625;  // degree per revolution
AccelStepper stepper(AccelStepper::HALF4WIRE, motorPin1, motorPin3, motorPin2, motorPin4);
unsigned long previousMillis = 0;     // Previous millis
unsigned long elapsedMillis = 0;      // Elapesed millis since touch
int ledState = LOW;                   // Current LED state

{
  pinMode(7, INPUT);
  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, LOW);
}

{
  // If the stepper isn't moving and doesn't have to go any distance
  if (!stepper.isRunning() && stepper.distanceToGo() == 0)
  {
    // Move the stepper to the degrees on the position of stepIndex in steps[]

    // Increase the index when the movement has been finished
    stepsIndex++;
    // If we have executed all positions of steps[]
    if (stepsIndex > stepsCount)
    {

  stepper.run();
}

}

This part:

{
  pinMode(7, INPUT);
  pinMode(LED_BUILTIN, OUTPUT);
  digitalWrite(LED_BUILTIN, LOW);
}

is outside of a function. This belongs in the setup. Without brackets.

Here:

float degToSteps(float deg)
{
  return (stepsPerRevolution / degreePerRevolution) * deg;
}
}


// Calculate the elapsed seconds
elapsedMillis = millis() - previousMillis;

// If the sensor is touched AND
// the elapsed time is larger than the given debounce time
if (digitalRead(8) == HIGH && elapsedMillis > debounceTime)
{
  // Set ledState to LOW if it was HIGH and vice versa
  if (ledState == HIGH)
  {
    ledState = LOW;
  }
  else
  {
    ledState = HIGH;
  }
  // send ledState to the builtin LED
  digitalWrite(LED_BUILTIN, ledState);
  // Store the current millis on the previous millis
  previousMillis = millis();
}

one closing bracket "}" is too much.
The whole part from // Calculate the elapsed seconds is also outside a function.

If this is sorted correctly, then it should compile.

in this line:
elapsedMillis = millis() - previousMillis;
it shows the error code: exit status 1
'elapsedMillis' does not name a type... what do I have to do

6

looks lke this block of code delimited by the braces "{", "}" is outside any function definition

and again near the bottom.
there's also that extra closing brace, "}"

not sure what the code is intended to do. it's better to build the code up in stages, a little at a time, testing each change, making sure it compiles and that it does what is expected

Read post #4 again. Post #6 probably as well but I did not read that one in detail.
