| SMS sender | |
| This sketch, for the Arduino GSM shield,sends an SMS message | |
| you enter in the serial monitor. Connect your Arduino with the | |
| GSM shield and SIM card, open the serial monitor, and wait for | |
| the "READY" message to appear in the monitor. Next, type a | |
| message to send and press "return". Make sure the serial | |
| monitor is set to send a newline when you press return. | |
