 SMS Alarm
 
 This sketch, for the Arduino GSM shield, made for Arduino SMS-Alarm.
 
 Advantages: minimum power consumption - only for Pirodetector. 
 Maximum time working from battery.
 (Battery charger included to schematic)
 
 Disadvantages: long time to send SMS - about 15 seconds.
 During this time you deactivate alarm with secret switch.
 
 How does it work:
 1) дежурный режим:Arduino UNO + GSM is power OFF. Pirodetector is powered On.
 2) When Alarm: When pirodetector set 1=5V (alarm)
 3) Power ON: Arduino UNO+GSM is power on.
 4) Self power On: Arduino UNO sets DPIN 5 = 1(5V). While DPIN 5 == 1(5V) Arduino UNO Power is on.
 5) Check switch: If secret switch is on - no Alarm. 
 +led On(DPIN 13,4)
 +Wait 30 seconds == time to set alarm to active mode and go out.
 +Switch power OFF. (DPIN 5 = 0(0V))
 6) If Switch OFF - Alarm Active mode.
 7) sends an SMS message
8) wait 20 seconds( between SMS). 
+blink led ((DPIN 13,4))
+power OFF. 

How to use it:
1) Assemble schematic. Connect GSM shield to arduino Uno.
Select switch on GSM Shield to "power from UNO board".
connect lead acid 12V battery and power supply 15V(from notebook).
2) Change phone nomber to you own:
(stored in array txtMsg[]) to phone number remoteNum[20]. 
3) Test it
4) Enjoy
5) you can debug it on hyperterminal.
