### Highlights ###

* System has been designed for 3 classrooms each fitted with one arduino system with each classroom having 3 batches(referenced as divisions in the code)

* Attendance starts after identification of admin finger(ids 180 and above)

* Stores Time, Date, Student Roll Number in 6 files(max 40 records each, you can increase as per requirement)

	* This was implemented so that it doesnt overload the sync function(below)

* Sync function sends data to remote server on the network periodically and runs lightshow function when idle

* Fully Functional Enrollment Modules(i.e. functions) with error control, error count and automatic try again

	* Continous Enrollment

	* Selected ID Enrollment

* Fully Functional Delete Modules(i.e. functions) 

	* Delete Selected ID

	* Delete Selected Division

	* Delete Whole Database

* Web Server recieves data, checks timetable for subject and inserts data into respective subject table

* Web Server Modules

	* Login

	* Admin Management

	* Subject Management

	* Timetable Management

	* Student Management

	

### Known Issues ###

* Ethernet and SD Card Modules cannot communicate simultaneously
(Hopefully someone solves it)

* The database file got lost during the process, you will have to make your own database
