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.

Circuit:
|
||
|
|
* GSM shield
|
||
|
|
* SIM card that can send SMS
