The project conditions are:The project functionality will be provided as per the project description suppliedbelow.You must present/demonstrate the project as a group, at the given time,andwithin a given time limit ( 20 mins ).A soft copy of all project documents is required before you
The program functionality should be as follows:• Upon entering the “run” mode all counters/timers must be reset (use the first scan bit).• When students scan RFID cards, the opening motor automatically opens the door and closing motor closes it after a 5 second wait.• The current number of students should be counted by incrementing/decrementing as students enter or leave the classroom. • The number of students entering the classroom is counted using a reflective sensor, while the number leaving is counted using a fiber optic sensor. The count should be displayed in the decimal tag "Total no of students”.• The maximum number of students in the classroom is 20, and when the classroom is occupied by the…
