I have designed and built an alarm for my house and have the need for remote monitoring.
I would like to incorporate an autodialer to phone preset numbers and send sms text messages. I would like to build a GSM module but will settle for a standard phone dialer for starters.
Can anyone recommend a good book or some decent links on the subject.
