Sending out SMS with the Arduino and SMSPI

This is an example of sending a free SMS with Arduino board using free SMS service supported by http://www.smspi.co.uk of England. This board can be implemented easier with an Arduino board and Ethernet Shield. (but, running a test after signning up http://www.smspi.co.uk service is inconvenient)

You can get the source code and more details from below link.
