Hello,
I am trying to design a magnetic strip card reader (using arduino) that sends info from the swipe to a cell phone via the GSM network.
Im a newbie with a basic understanding of coding. I found some code (http://cal.freeshell.org/wp-content/uploads/2009/11/mag_read.pde) for a magnetic card reader, but Im kind of confused. I see that the code returns numbers, but how would I go about writing code that sends the returned characters in a single string over SMS?
Thank you in advance!
