Ok I have tried that sketch but I can't figure it out... I need help trying to figure out how to keep track of how many steps the stepper takes from when it is powered up and if I can get that then I should be able to get the rest... any ideas on how to do this? Here is my code....

Code:

#include <Stepper.h>

Stepper myStepper = Stepper(200,8,9,10,11);

int ledpin = 13;
int pirpin = 4;
int pirstate = 0; // variable to store current pir state
int lastpirstate = 0; // variable to store last pir state
int pirpin2 = 7;
int pirstate2 = 0;
int lastpirstate2 = 0;
int bothpirstate = 0;
int lastbothpirstate = 0;


void setup() {
 
  myStepper.setSpeed(60); // sets speed of stepper
 
  pinMode(ledpin, OUTPUT);
  pinMode(pirpin, INPUT);
  pinMode(pirpin2, INPUT);
}

void loop() {
 
  int pirpinstate = digitalRead(pirpin);
  int pirpin2state = digitalRead(pirpin2);
  const int pos1 = 50;
  const int pos2 = 100;
 
 
 pirstate = digitalRead(pirpin);
 
  if(pirstate != lastpirstate) {
    if(pirstate == HIGH) {
    digitalWrite(ledpin, HIGH);
    myStepper.step(pos1);
  } else {
    digitalWrite(ledpin, LOW);
    myStepper.step(-pos1);
  }
}
lastpirstate = pirstate;

  pirstate2 = digitalRead(pirpin2);
 
  if(pirstate2 != lastpirstate2) {
    if(pirstate2 == HIGH) {
      digitalWrite(ledpin, HIGH);
      myStepper.step(pos2);
    } else {
      digitalWrite(ledpin, LOW);
      myStepper.step(-pos2);
    }
  }
lastpirstate2 = pirstate2;
}

Thanks PaulS when PIR1 is HIGH and PIR2 is HIGH is when i get confused on my programming... I will try your sketch!! thanks!

Ok sorry for being unclear....

when pir1 senses motion i want stepper to step 50 steps counter clockwise
when pir1 is low(no motion) and pir2 senses motion i want stepper to step 100 steps counter clockwise
when pir1 is senses motion (already at the 50 step counter clockwise position) and then pir2 senses motion I want stepper to step 50 steps counter clockwise (to reach the position it supposed to be at when just pir2 senses motion.)

does that make more sense?

thanks

Ok thanks for your help and now that I have got that figured out I would like to add a few more pir sensors. Here is what I want to accomplish... When pir#1 goes high(senses motion) the stepper will turn to that direction and stop until it goes low then return to original position. Ok so far the sketch I have works perfectly for that. Now I add pir#2... when pir#1 is high and pir#2 goes high then it rotates to far. If pir#1 is low and pir#2 goes high then the stepper turn to the right position and works fine. Does this make sense?? Here is the code...

do I need to use interrupts to accomplish this?

thanks

Code:

#include <Stepper.h>

Stepper myStepper = Stepper(200,8,9,10,11);

int ledpin = 13;
int pirpin = 4;
int pirstate = 0; // variable to store current pir state
int lastpirstate = 0; // variable to store last pir state
int pirpin2 = 7;
int pirstate2 = 0;
int lastpirstate2 = 0;
int LED = 12;

void setup() {
 
  myStepper.setSpeed(60); // sets speed of stepper
 
  pinMode(ledpin, OUTPUT);
  pinMode(pirpin, INPUT);
  pinMode(pirpin2, INPUT);
  pinMode(LED, OUTPUT);
 
}

void loop() {
 
  pirstate = digitalRead(pirpin);
 
  if(pirstate != lastpirstate) {
    if(pirstate == HIGH) {
    digitalWrite(ledpin, HIGH);
    myStepper.step(50);
  } else {
    digitalWrite(ledpin, LOW);
    myStepper.step(-50);
  }
}
lastpirstate = pirstate;

  pirstate2 = digitalRead(pirpin2);
 
  if(pirstate2 != lastpirstate2) {
    if(pirstate2 == HIGH) {
      digitalWrite(ledpin, HIGH);
      myStepper.step(-100);
    } else {
      digitalWrite(ledpin, LOW);
      myStepper.step(100);
    }
  }
lastpirstate2 = pirstate2;

}

hey I got it!!! :-) thanks for ya'lls help!!! here is the code i came up with...

Code:

#include <Stepper.h>

Stepper myStepper = Stepper(200,8,9,10,11);

int ledpin = 13;
int pirpin = 4;
int pirstate = 0; // variable to store current pir state
int lastpirstate = 0; // variable to store last pir state
int pos = 50;
int pos2 = -50;

void setup() {
 
  myStepper.setSpeed(60); // sets speed of stepper
 
  pinMode(ledpin, OUTPUT);
  pinMode(pirpin, INPUT);
 
}

void loop() {
 
  pirstate = digitalRead(pirpin);
 
  if(pirstate != lastpirstate) {
    if(pirstate == HIGH) {
    digitalWrite(ledpin, HIGH);
    myStepper.step(pos);
  } else {
    digitalWrite(ledpin, LOW);
    myStepper.step(pos2);
  }
}
lastpirstate = pirstate;
}

here is my latest sketch.... i'm getting hung up on my delay function or do I need to use a variable to store the value of the "pirpin"?? I am fairly new to this :-) if you can't tell but am willing to learn

Code:

#include <Stepper.h>

Stepper myStepper = Stepper(200,8,9,10,11);

int ledpin = 13;
int pirpin = 4;

int pos = 50;
int pos2 = -50;

void setup() {
 
  myStepper.setSpeed(60); // sets speed of stepper
 
  pinMode(ledpin, OUTPUT);
  pinMode(pirpin, INPUT);
 
}

void loop() {
 
  if (digitalRead(pirpin) == HIGH) {
    digitalWrite(ledpin, HIGH);
    myStepper.step(pos);
  }
 
  if(digitalRead(pirpin) == LOW) {
    digitalWrite(ledpin, LOW);
    myStepper.step(pos2);
  }
}

Thanks for you help so far! :-) I have written a simple code to control the stepper and have it stop at 90, 180, 270, and 360 degrees then rotate back to the original starting position. It delays 1 second at each spot but I want it to stay there for as long as the pir stays high. If I take out the " delay(1000);" then it just keeps spinning until the pir goes low. Does this make sense? I will be glad to clarify more!

Here is the code...

Code:

#include <Stepper.h>

Stepper myStepper = Stepper(200,8,9,10,11);

int pos = 50;
int pos2 = 50;
int pos3 = 50;
int pos4 = 50;
int pos5 = -200;

void setup() {
 
  myStepper.setSpeed(60);
 
}

void loop() {
 
  myStepper.step(pos);
  delay(1000);
  myStepper.step(pos2);
  delay(1000);
  myStepper.step(pos3);
  delay(1000);
  myStepper.step(pos4);
  delay(1000);
  myStepper.step(pos5);
  delay(1000);
 
}

yes I have looked at those sketches but all they do is either go by one step at a time or keep rotating back and forth. And that is not what I want. I want to be able to tell the motor to turn to position x and stay there all day if need be...not keep moving.

Ok I am working on a project and this is what I would like to do.

When pir sensor senses motion this stepper motor https://www.sparkfun.com/products/9238? with this motor driver https://www.sparkfun.com/products/10267? would turn 90 degrees and stay there until the sensor goes low(stops sensing motion).

My question is... how do I write a simple sketch to accomplish this?

Here is my sketch that I want to insert the new stepper sketch into...

Code:

#define DIR_PIN 2
#define STEP_PIN 3

const int sensorPin = 4;
const int ledPin = 13;

void setup() {
  pinMode(DIR_PIN, OUTPUT);
  pinMode(STEP_PIN, OUTPUT);
  pinMode(sensorPin, INPUT);
  pinMode(ledPin, OUTPUT);
}

void loop(){
 
  if(digitalRead(sensorPin) == HIGH) {
    digitalWrite(ledPin, HIGH);
  }

if(digitalRead(sensorPin) == LOW) {
  digitalWrite(ledPin, LOW);
}
}

Looks really nice!! How did you make your housing for it?

Thank ya'll for your help!! I wish I would have done more research on servo's before I bought one but oh well I'll find a use for it sometime. But yea I have decided to go with a stepper motor maybe one like this one https://www.sparkfun.com/products/10551 and use this motor driver https://www.sparkfun.com/products/10267 . Do you think this is a good choice or would you recommend something else?

Thanks again 

I am working on a project and need a servo that rotates 360*. Here is what i would like to accoumplish. Have 4 pir sensors pointed in 4 different directions. When one of those senses movement my arduino uno will tell a servo to turn to that sensor. And i will have a camera mounted to it also to take a pic. So my question is.... does someone make a servo that would work for my project? Thanks for your help!

thanks PaulS

just in case you haven't figured it out by now I'm a beginner so any advice would be appreciated!!

the line i made runs perpendicular with the white plastic arm
