Thanks Robin2,
i have removed the while from the code, and attempting to write the code correctly.
I have wired a pir motion sensor up to the arduino, i want the stepper to turn a 100 steps clockwise and then 100 steps counter clockwise when the pir is triggered. Im still new to coding, and have relied upon the arduino sample code for the pir and its not working. can you see the fault in the code?
Heres the code:
#include <AccelStepper.h>
AccelStepper stepper (1,3,2); // name of stepper motor (1 = driver, pin 3 = step, pin 2 = direction)
int pirPin = 4; //the digital pin connected to the PIR sensor's output
int calibrationTime = 30;
//the time when the sensor outputs a low impulse
long unsigned int lowIn;
//the amount of milliseconds the sensor has to be low
//before we assume all motion has stopped
long unsigned int pause = 5000;
boolean lockLow = true;
boolean takeLowTime;
void setup() {
stepper.setMaxSpeed(1000);
stepper.setAcceleration(200);
Serial.begin(9600);
pinMode(pirPin, INPUT);
digitalWrite(pirPin, LOW);
//give the sensor some time to calibrate
Serial.print("calibrating sensor ");
for(int i = 0; i < calibrationTime; i++){
Serial.print(".");
delay(1000);
}
Serial.println(" done");
Serial.println("SENSOR ACTIVE");
delay(50);
}
void loop()
{
if(digitalRead(pirPin) == HIGH){
stepper.moveTo(100);
{ stepper.run(); }
stepper.moveTo(100);
{ stepper.run(); }
if(lockLow){
//makes sure we wait for a transition to LOW before any further output is made:
lockLow = false;
Serial.println("---");
Serial.print("motion detected at ");
Serial.print(millis()/1000);
Serial.println(" sec");
delay(50);
}
takeLowTime = true;
}
if(digitalRead(pirPin) == LOW){
if(takeLowTime){
lowIn = millis(); //save the time of the transition from high to LOW
takeLowTime = false; //make sure this is only done at the start of a LOW phase
}
//if the sensor is low for more than the given pause,
//we assume that no more motion is going to happen
if(!lockLow && millis() - lowIn > pause){
//makes sure this block of code is only executed again after
//a new motion sequence has been detected
lockLow = true;
Serial.print("motion ended at "); //output
Serial.print((millis() - pause)/1000);
Serial.println(" sec");
delay(50);
}
}
