Make Voice Call
|
|
|
|
This sketch, for the Arduino GSM shield, puts a voice call to
|
|
a remote phone number that you enter through the serial monitor.
|
|
To make it work, open the serial monitor, and when you see the
|
|
READY message, type a phone number. Make sure the serial monitor
|
|
is set to send a just newline when you press return.
|
|
|
|
Circuit:
|
|
* GSM shield
|
|
* Voice circuit.
|
|
With no voice circuit the call will send nor receive any sound
