design a rotary car storage system
design a way to have the cars stored in that system
have an RFID tag, bring your own, or use one from the lot
you park on the pad, get out of the car
swipe your RFID tag,
then design an Arduino program that will know what spaces are used. and what ones are not.
automatically move the car into an un-used space, remember the space and link it to the RFID tag.
log the time in.
now, when the customer comes back and scans their RFID tag, the arduino will signal your rotary system to bring the car for the person.
pretty much sums it up.
I would suggest you start by getting an Arduino and try out the example programs.
Thank you so much for your advice.
Actually, I am not so clear about what a rotary car storage system is. I am stuck in this stage.
in my idea, my arduino project will have a random code generation process and will be shown on the Nokia 5110 display (simulating the printing of receipt)
when people take car, there is a keypad for people to input their code for their own car and the corresponding car slot moves to the ground level.
I am planning that each car slot will have different resistor connected in it and therefore each car slot will have a unique resistor reading.
And the random generated code will map with the corresponding car slot by the unique resistor reading.
like the above, I am imagining should I use the database concept to construct the above system?
is the database concept is the only way?
I searched on the internet and know that we can save .txt data to the SD card module, however, can we read the .txt file in the SD card module to get the corresponding linkage for the right car?
it seems that arduino is not good at managing the database and are there any simpler ways that we can still achieve goal?
every single step is easy, but it is hard to integrate all the processes into an automatic system.
and am I making things complicated?
are there any suggestions can make things going easier?
