Question

I want to use a stepping motor to control the number of steps it moves. I set the “step revolution” to 60 and I set the number of steps to 1. But it hasn’t stopped for a long time and has been walking.

I am using a Arduino IDE to make a writing machine (X-Y Plotter)

It would be better if you could give me the code and explain it.

Answer 1

#include <Stepper.h>
int steps_per_revolution = 32; // change this to fit the number of steps per revolution for your motor

Stepper my_stepper(steps_per_revolution, 8, 9, 10, 11); // initialize the stepper library on pins 8 through 11: 

void setup() {
   Serial.begin(9600);
   myStepper.setSpeed(5);
}

void loop() {
   Serial.println("clockwise");
   my_stepper.step(steps_per_revolution);
   delay(500);

   while(1){}

}

Explaination:

You are moving the motor in your "void loop" function. That's why it keeps on going. I have moved the stepper motor in my code one step and then I have put the program in an infinite loop so it prevents the calling of the loop function again. If you want to use the stepper only once in the beginning, you can write your stepper commands in "void setup" function. Or for your writer bot, you need to use the stepper, again and again, so you can put the stepper commands in a function and call them whenever you need that in the program and rest of the time you can perform your other tasks. The arguments of function can be the number of steps you need it to move. Direction can be decided by changing the sign of the passed arguments. Like the one below:

void stepper_move(steps)

{

my_stepper.step(steps);

delay(500);

}
