First post here, but I have some interesting projects that I would appreciate some help with. I'm posting this in the C section, just because I have had a little experience with C.
I know there is a ton of info on the subject around the web, but it makes more sense to me to get application specific answers at this point so here we go.
I'm gonna keep this thread for this specific project so that it is all in one place. So I am going to start at the beginning. I can't reveal everything about this project, but I want to start with a basic question that will decide whether or not to continue with this.
I am trying to interface a fingerprint reader with an automotive ignition device for concept that I am working on. Can anyone help me with the basic necessities of a project like this. What kind of hardware will I need? etc.
I need the reader to be pressure sensitive, when pressed, read the fingerprint, and if the fingerprint match is positive, turn the "key" to the on position (the starter button is separate), if the fingerprint match is negative, sound some type of alarm.
So I guess that would be my rough algorithm right there. Can I do this with a C program in an eeprom chip to control the reader?
Well, I better stop there, before I get carried away. Thanks in advance!
