So I'm almost completely new to ardunio, we've been given a project at university and although we dont need a working model we need a technical report and be able to explain how this may work.
We're thinking of implementing a Car breathalyser test, so drivers must take a breathalyser test the first time they attempt to drive the car.
The driver will turn the ignition on which will power the system, a finger print scanner will be in place so only certain users may drive based on them passing or not. The system will identify the user for the rest of the day so if they have passed they only need to rest their fingerprint on the scanner or if they have failed they can retake the test. Should they fail the test the car will not start, how will we do this?
Anyone able to help us with how this may work?
