Please i need help i m doing my final year project...... what i want is when send sms "On" led should turn on and when i send sms "Off" led should turn off but when i send sms "Off" PIR sensor should start work..... but i dont know its not working here is my code please anyone can help meee
#include "SIM900.h"
#include <SoftwareSerial.h>
//#include "inetGSM.h"
#include "sms.h"
SMSGSM sms;
int numdata;
boolean started=false;
char smsbuffer[160];
char n[20];
int ledPin = 13; // led connected to control pin 13
int PIRSensor = 2; // the PIR sensor will be plugged at digital pin 2
int val=0;
void setup() {
pinMode(ledPin, OUTPUT); // declare the ledPin as as OUTPUT
pinMode(PIRSensor, INPUT); // declare the PIRSensor as as OUTPUT
Serial.begin(9600); // use the serial port
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower.
if (gsm.begin(2400)){
Serial.println("\nstatus=READY");
started=true;
}
else Serial.println("\nstatus=IDLE");
if(started){
//Enable this two lines if you want to send an SMS.
//if (sms.SendSMS("3471234567", "Arduino SMS"))
//Serial.println("\nSMS sent OK");
}
};
void PIRON(){
if(digitalRead(PIRSensor==HIGH)){ // read the input pin
digitalWrite(ledPin, HIGH); // sets the LED to the button's value
delay(1000);
digitalWrite(ledPin, LOW); // delay in milisecond. 3000 = 3 second
}
}
void loop() {
if(started){
//Read if there are messages on SIM card and print them.
if(gsm.readSMS(smsbuffer, 160, "On", 20))
{
digitalWrite(ledPin, HIGH);
Serial.println(n);
Serial.println(smsbuffer);
}
if(gsm.readSMS(smsbuffer, 160, "Off", 20))
{
digitalWrite(ledPin, LOW);
PIRON();
Serial.println(n);
Serial.println(smsbuffer);
}
delay(1000);
}
