hiya i am very new to raspberry pi so need a bit of help with the coding
i am looking to make a queuing system for a classroom for when students ask for help they don't get skipped in the queue of students also asking for help from the teacher.
so what would happen is that when a student needs help they will flick a switch at their desk which will send a message to the raspberry pi. the pi will then send a message to a 7 seg display to show they computer that needs help.
as soon as the switch is also switched it will start a 5 minute timer which is the maximum amount of time each student gets for help.
if the 5 minutes runs out a bell and strobe light will go off to show the 5 minutes is up and the teacher will move on to the next student and flick the students switch off.
if the student the help that is needed before the 5 minutes is up, the switch will be switched off which will cancel the 5 minutes for that user.
if there is a next student in the queue the 5 minutes will then start for them as soon as they become first in the queue.
i hope this makes sense and would be great if i could get some help on it.
