Please i have compile this code without any error but when i upload it to arduino it seems not to work..am not getting any sms alert ..is there any thing wrong with this code ?
#include <SoftwareSerial.h>
SoftwareSerial SIM900(0, 1);

* PIR sensor tester
*/
int ledPin = 13; // choose the pin for the LED
int inputPin = 2; // choose the input pin (for PIR sensor)
int pirState = LOW; // we start, assuming no motion detected
int val = 0; // variable for reading the pin status
void setup()
{
pinMode(ledPin, OUTPUT); // declare LED as output
pinMode(inputPin, INPUT); // declare sensor as input
Serial.begin(9600);
SIM900.begin(9600);

delay(1000);
digitalWrite(13, LOW);
delay(5000);
}
void sendSMS()
