sms auto print

Just wondering if arduino is able to recieve an sms and automatcaly send it to a printer. And also do auto reply?

Yes, you need : 1) a GSM shield - e.g. - - and - -

2) a serial printer (other printers are more difficult) - e.g. - - but you probably can find some on eBay too

3) an appropiate sketch - that will take quite some puzzling but it is done before


You can implement GSM part much easier. USB Host Shield and an old phone will cost quite a bit less than GSM shield and won't take precious serial port . You can also reuse both shield and phone when you get bored. See here ->
