I'm a beginner in this Arduino platform and all of its related components.
I'm planning on a project for parking system using Arduino, (only on a small scale and not in the real scale). My idea is a sensor that can detect the movement of a car, and then, in some range, it will trigger a RFID reader to detect the RFID tag. If there is RFID tag and it is true, then it will show a green light for example. Otherwise, I'm thinking about having an alarm system that will indicate that there is no RFID tag detected or the RFID may be not true. Probably it is as simple as having LED bulb or maybe a buzzer.
I really need your guys' expertise on this whether my project is possible or need an adjustment or not possible at all.
Thank you so much in advance!
