sensor calibration delay

Development Tools IDE 1.x

hi does anyone know how to tell the Arduino to ignore the values from a PIR sensor for the first 40 seconds

2

Put a delay() in setup()?

I tried it with delay but it still lights up the led on my other Arduino(sorry about the bother I am new to this)

pir.ino (841 Bytes)

Just POST the damn code.

#include <SoftwareSerial.h>
#include <XBee.h>


//Reads and analog sensor and displays the value
int sensePin = 0;
int ledPin = 9;
SoftwareSerial XBee(0,1);// pins of xbee(RX,TX)
void setup()
{delay(41000);}
{
  //We don't need to specifiy sensor Pin as an input, since it defaults to that when we read it

  //This is the default value, but we can set it anyways
  analogReference(DEFAULT); //5V Reference on UNO

  pinMode (ledPin,OUTPUT);//Setting the led pin as a output
  
  //Allows us to listen to serial communications from the arduino
  Serial.begin(9600);
  XBee.begin(9600); 
}

void loop()
{

int val = analogRead(sensePin);//telling the arduino to read the value of the sensor

if (val > 500) 
{
  digitalWrite (ledPin,HIGH);
digitalWrite (1,HIGH);
}
else 
{
  digitalWrite (ledPin,LOW);
digitalWrite (1,LOW);
}
  delay (50);
}

That doesn't actually compile, does it?

09aadarsh:
it does compile.

Not as posted, it doesn't.

I get this error:

expected unqualified-id before '{' token

This } closes setup() so the rest is outside any function:

void setup()
{delay(41000);[b][color=red]}[/color][/b]
