Arduino stepper motor elevator.

Using Arduino Programming Questions

Ok heres my code so far.

#include "Stepper_28BYJ_48.h"

const int buttonPin1= 2;    
    

int floorState = 3;
Stepper_28BYJ_48 stepper(6, 5, 4, 3);

void setup() {
  pinMode(buttonPin1, INPUT);
  Serial.begin(9600);
}

void loop() {
int buttonState1;         
  buttonState1 = digitalRead(buttonPin1);


  // check if the pushbutton is pressed. If it is, the buttonState is HIGH:
  if (buttonState1 == HIGH) {

  if (floorState == 3){
    stepper.step(-1);
    int floorState = 1;
  }
}
 

}

I need to be able to push a button once and it execute the stepper motor to move like 2 steps down. I have wired everything up and when I press the button it just turns off after I unpress it. Any help.

I would suggest you look at some of the stepper examples in the IDE (File->Examples->Stepper) to get an idea of how to control a stepper motor. Having it move 1 step isn't going to accomplish much.

You also do not need to declare 'floorState' again inside your if() statement. That creates a new variable, separate from your global 'floorState' variable and then it immediately goes out of scope when the if() statement is over. Just assign a value to it 'floorState = 1' without the 'int' part. I'm not really sure what this code will accomplish because once you change the value of 'floorState' the if() statement will never execute again.

What video? I think I found it in this Thread. I have suggested that the Threads be merged.

PS ... I find it helps to hold my laptop in my hands and move it in time to counteract the movement of the camera. :slight_smile:
