hi guys,
i want to make a project using local telephone line and at89c51 microcontroller. my project should work like this.
suppose there is some institute which takes admission on the basis of entrance score obtained by the candidate. now to know the result the candidate dials the number of that institute. the instrument should pick up the phone and tells the caller to input his roll no. after that candidate dials his roll no. this instrument should check his roll no if he has passed and then replies him what's his result is and hangs up the telephone. this is the idea of the project.
so if you guys have any idea then please reply soon. this project i want to do is actually for my college graduation. thanks
