ok i need to merge two codes together to make one. I need my servo to move 90 degrees when the PIR Sensor is activated. and yea thats about is. so i have these two codes.


This code is for the PIR Sensor. When the sensor is activated it makes a light and oiezo speaker light, and buzz.

/////////////////////////////
//VARS
//the time we give the sensor to calibrate (10-60 secs according to the datasheet)
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; 

int pirPin = 3;    //the digital pin connected to the PIR sensor's output
int ledPin = 13;


/////////////////////////////
//SETUP
void setup(){
  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);
  }

////////////////////////////
//LOOP
void loop(){

     if(digitalRead(pirPin) == HIGH){
       digitalWrite(ledPin, HIGH);   //the led visualizes the sensors output pin state
       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){       
       digitalWrite(ledPin, LOW);  //the led visualizes the sensors output pin state

       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);
           }
       }
  }



This simply makes the servo move 90 degrees whan power goes throught the arduino

#include <Servo.h>
 
Servo myservo;  // create servo object to control a servo
Servo myservo2; // a maximum of eight servo objects can be created
 
int pos = 90;    // variable to store the servo position
 
// set a variable to store the byte sent from the serial port
int incomingByte;
 
void setup() {

  // start sending data at 9600 baud rate
  Serial.begin(9600);
  myservo.attach(9);    // attaches the servo on pin 9 to the servo object
  myservo2.attach(10);  // attaches the servo on pin 10 to the servo object

}
 
void loop() {
  // check that there's something in the serial buffer
  if (Serial.available() > 0) {
    // read the byte and store it in our variable
    // the byte sent is actually an ascii value
    incomingByte = Serial.read();
    // note the upper casing of each letter!
    // each letter turns a motor different way.
   
    // start of left laser sweep, moving left 90 degrees.
    // arrow laser spins and points to left.
    if (incomingByte == 'L') {
    Serial.println(incomingByte);
   
    myservo2.write(180);                         // send servo 2 to the 180 degree position and stay
    for(pos = 180; pos > 90; pos -= 1)  // goes from 90 degrees to 180 degrees
  {     // in steps of 1 degree
    Serial.println(pos);
    myservo.write(pos);    // tell servo to go to position in variable 'pos'
   
    delay(15);                       // waits 15ms for the servo to reach the position
  }
    for(pos = 90; pos<=180; pos+=1)     // goes from 180 degrees to 90 degrees
  {                               
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
    }
    }
   
   
    // start of right laser sweep, moving right 90 degrees.
    // arrow laser spins and points to right.
   
    if (incomingByte == 'R') {
     Serial.println(incomingByte);
     Serial.println(pos);
    myservo2.write(0);                          // send servo 2 to the 0 degree position
    for(pos = 0; pos < 90; pos += 1)  // goes from 90 degrees to 0 degrees
  { Serial.println(pos);                                 // in steps of 1 degree
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
  }
    for(pos = 90; pos>=0; pos-=1)     // goes from 0 degrees to 90 degrees
  { Serial.println(pos);                               
    myservo.write(pos);              // tell servo to go to position in variable 'pos'
    delay(15);                       // waits 15ms for the servo to reach the position
    }
    }
   
    // if a S is sent make sure the servos go to 90 degrees
    if (incomingByte == 'S') {
    Serial.println(incomingByte);
    Serial.println(pos);
    myservo2.write(90);
    myservo.write(90); 
     
     
     
     
    }
  }
}

Some reading that might help you.

Thamkyou so much KE7GKP but it is putting an error when i compile it...... it high lights

Code:

       myservo.write(180);         // send servo to the 180 degree position and stay

and says that "myservo was not declared in this scope"

[Reply #3 on:]

So,you need to declare "myservo" in scope.
I'd help you more, but I can't see your code.
