I am working on student café double existence check on feeding time using arduino, crystal LCD screen, finger print and buzzer.
The purpose for the project is to control repeated existance on café on Sigle period. the project will have reset button to refresh on breakfast, lunch and dinner time. so i am in need for code for this project. please anyone can help me ?
No, didn't get any of that.
Do you have a specification?
Never heard of any such code.
Do you want ready made code or do you want help writing code?
For the first I can move this for you to the section where you can pay someone to write code for you.
For the second you need to show some effort yourself and ask for help when you get stuck.
I want support on writing the code, I appreciate if any ready made code is available!
Do you have the hardware?
If you want to write code the general idea is to start with the tutorials on this site and with the examples in the IDE. You seem to be asking either for someone to write the code for you, which generally requires payment, or for personal tuition. I assume you are a complete beginner, you might be surprised to learn you are not the first. The tutorials and other training materials were written with people like you in mind, you just need to start at the beginning and learn.
Have you successfully used the three components separately?
Until you have done three programs, one each to test (and learn about) the 1) LCD screen, 2) buzzer and 3) finger print (reader?), it will be hard to get them all working together.
And after you have done, it will be easy. Well, easier.

Sure, yes
Great.
What have you done so far?
sure, I am beginner for coding. thank you for your suggestion and comment!
How many people do you need to identify? Different fingerprint readers have different limits on how many people can be registered at the same time.
100 people maximum! thank you!
Fix that first
I have finished the passible integration connection for the buzzer and the screen as an output and the fingerprint as an input with an arduino uno.
I'm not a dentist, and I hate pulling teeth.
Goodnight
thank you for your suggestion! the integration is need on this project.
@ezedinkamil When is this due to be handed in? Do you need just the code, or do you need the theisis of operation provided as well?
I can not replay you my circuit picture as a replay. it is not working replaying picture rather than text. please kindly send me your email and will send you my hardware. thank you Awol!
The DFRobot SEN0348 can only hold 80 fingerprints so the capacity is definitely something to look at when picking a sensor.
This one says it can store 1000 fingerprints:

This one stores 250:

They both use a serial interface so it would be good to have an Arduino with a spare hardware serial port like the Leonardo/Micro or the MEGA.
