Control your Arduino by SMS via GPS/GPRS/GSM Module V3.0

// Product name: GPS/GPRS/GSM Module V3.0
// # Product SKU : TEL0051
 
// # Description:
// # The sketch for controling the GSM/GPRS/GPS module via SMS.
// # Steps:
// #        1. Turn the S1 switch to the Prog(right side)
// #        2. Turn the S2 switch to the USB side(left side)
// #        3. Plug the GSM/GPS jumper caps to the GSM side
// #        4. Upload the sketch to the Arduino board(Make sure turn off other Serial monitor )
// #        5. Turn the S1 switch to the comm(left side)    
// #        6. Turn the S2 switch to the Arduino(right side)       
// #        7. RST the board until the START led is on(make sure you have >6V power supply)
// #        8. Plug the long side of LED into pin 8 and short side into GND
// #        9. Start sending "LH" and "LL" to your board to turn LED on and off.

 *  created:    2013-11-14
 *  by:     Grey
 *  Version:    0.3
 *  Attention: if you send the wrong SMS command to the module, just need to press RST.
 *  This version can't watch the module status via the serial monitor, it only display the Arduino command.
 *  If you want to watch the status,use the SoftwareSerial or the board with another serial port plese.

// # The sketch for controling the GSM/GPRS/GPS module via SMS.
// # Steps:
 
// #        1. Curved the pin 0 and 1. Make sure when you plug the module to UNO, they won't connect to the RX and TX.
