Door Alarm system
devices need
1. Arduino
2 GSM Shield
3. Reed Switch

Code:



char incoming_char=0;
ReedSensor 7
byte lockOut = 0;
SerialGSM cell(2,3);
void setup()
{
Serial.begin(9600);
cell.begin(9600);

Serial.println("Starting GSM");
delay(30000);

cell.Verbose(true);
cell.Boot();
cell.DeleteAllSMS();
cell.FwdSMS2Serial();

}

void sendSMS(byte fun)
{
if(fun == 1)
{
cell.Rcpt("+91815###X660");
cell.Message("Arduino GSM Modem has started!");
cell.SendSMS();
}

if(fun == 2)
{
cell.Rcpt("+91815###X660");
cell.Message("Door has been opened!");
cell.SendSMS();
}
if(fun == 3)
{
cell.Rcpt("+91815###X660");
cell.Message("Door has been closed!");
cell.SendSMS();
}
}

void loop()
{
sendSMS(1);

while(1>0)
{

if(lockOut != 1)
{
if(digitalRead(ReedSensor) != 0)
{
sendSMS(2);
lockOut = 1;
Serial.println("Door has been opened! Lock out enabled!");
}
}
else
{
if(digitalRead(ReedSensor) == 0)
{
sendSMS(3);
lockOut = 0;
Serial.println("Door has been shut! Lock out disabled!");
}
}
if(cell.available() > 0 )
{
incoming_char=cell.read();
Serial.print(incoming_char);
}
if(Serial.available() > 0 )
{
incoming_char=Serial.read();
cell.print(incoming_char);
}
}
