Hi guys,I am new to this site.I am currently busy with my Electro Tech course.I need help regarding a project.I am finding some difiiculty because I did not do any Microcontrollers yet.I need to build a circuit that rings an alarm or bell at certain times.
The bell has to ring at
a)8:00 am
b)9:45am
c)10:00
d)11:45
e)12:15
f)14:00

It must run from Monday -Thursday 8am-2pm
friday 8am-12pm
Sat and sun it must be off.
It must also have a backup battery which must always maintain its charge.

I am not asking you guys to build the project for me.I just need guidelines.I am thinking of using 555 timers and counters but don't know how to integrate it.

Your assistance will highly be appreciated
 
hi.
This circuit is often used for school timing periods
