stepper motor programme

hello, i have been working on a machine for a while now, i have 3d printed out the parts i need, and now need to write the programme for the motor, its for a standard 5v stepper motor. i need the motor to rotate clockwise for a minute, and then anti clockwise for a minute. and then stop for mabye an hour.

i know i can use the "delay" command to make the motor stand still. but it still draws power and heats up, which would be a problem, because it cant get to hot in the machine.

i read that i could write:

digitalWrite(8,LOW);
** digitalWrite(9,LOW);**
** digitalWrite(10,LOW);**
** digitalWrite(11,LOW);**

to shut off the motor, which workes, but then thats it it just stays turned off it doesnt repeat the cycle of turning clockwise - anti clockwise - off for an hour - turning clockwise - anti clockwise - off for an hour...

ive never written any code before, so i dont know how to make it only turn off for a defined ammount of time. if anybody knows how to do this, could you help me out?

heres the code ive got so far:

#include <Stepper.h>
#define STEPS 2038
Stepper stepper(STEPS, 8, 10, 9, 11);
void setup()
{ **
** stepper.setSpeed(6);
** stepper.step(12228);**
** delay(0);**
** stepper.setSpeed(6);**
** stepper.step(-12228);**

** digitalWrite(8,LOW);**
** digitalWrite(9,LOW);**
** digitalWrite(10,LOW);**
** digitalWrite(11,LOW); **
}
void loop()
{}

The simplest way would be to move the code from setup() to loop() and add a
delay(1000UL * 60 * 60);  //wait for 1 hour
after digitalWrite(11, LOW);.

Of course nothing can happen during the delay. Better would be to use millis() for the timing so the program can do other stuff during the wait, if necessary.

Blink without delay().

  delay(0);

Read the how to use this forum-please read sticky to see how to properly post code. Remove useless white space and format the code with the IDE autoformat tool (crtl-t or Tools, Auto Format) before posting code.
Is just silly (useless ).

if your steppermotor gets really hot the current is to high for this steppermotor.
The current must be adjusted to a value which makes the stepper-motor's temperatur rise to maybe 35 °C.

Depending on the stepper-driver you are using there is an ability to switch off the current through the motor-coils with an enable-input.

So next thing is to write about the exact type of stepper-motor and steppermotor-driver you are using. A link to the website where you bought the steppermotor and the steppermotordriver.

Working with arduino and electronics is not superstandardised like installing an app on a smartphone or pluggin in any kind of USB-device into a computer

Working with arduino and electronics requieres a minimum of knowledge how to make it work.
Which means knowledge about programming and knowledge about electronics.

It is really OK that you are asking. But you have to provide a minimum of concrete details about the hardware that you are using to get suggestions that have a high chance to make your project work.

best regards Stefan

the solution was simple

#include <Stepper.h>
#define STEPS 2038

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

void setup() 
{}
void loop() 
{ 
 stepper.setSpeed(6);
 stepper.step(-1000UL * 60 * 1);
 delay(0);
 stepper.setSpeed(6);
 stepper.step(1000UL * 60 * 1);
 
 digitalWrite(8,LOW);
 digitalWrite(9,LOW);
 digitalWrite(10,LOW);
 digitalWrite(11,LOW);
 delay(1000UL * 60 * 60); 
}
