| 2 | SMS receiver
|
---|
| 3 |
|
---|
| 4 | This sketch, for the Arduino GSM shield, waits for a SMS message
|
---|
| 5 | and displays it through the Serial port.
|
---|
| 6 |
|
---|
| 7 | Circuit:
|
---|
| 8 | * GSM shield attached to and Arduino
|
---|
| 9 | * SIM card that can receive SMS messages
|
---|
| 10 |
|
---|
| 11 | ATTENTION: to work correctly with M0/M0 pro you have to connect pin 2 to pin 4 of the shield
