My relatives has a school, of little children, and sometimes the personal in charge of ringing the bell are very busy with some issues which comes with School Managing job; so, the schedules some times are not accomplished. So, I decided to build many years ago, a Timer capable to ring a bell, alarm, whatever attached to its relay at determinate times of day. All this first prototype, only using test PCB stripped boards, not in a finished PCB BOARD with professional quality. THIS YEAR, is the year.

LEARNING from the REAL PROTOTYPE, I figured out is BETTER to have the sections of the design separately, ie: Mainboard in a PCB, Power supply in other, RTC in other PCB, Relay for Bell separate, keypad, of course, etc; so, is more easily at maintenance time (change RTC 3v battery for example) or for repair some part broke. With that in mind, y design the School Timer 2024, PCB version, in separate KiCAD projects...

By the way, the PIC Microcontroller are NOT FINISHED... no matter Arduino make the things easy, the engineers still use the old way, and old way Teaches a lot more, in DETAIL... Now, with manufacturers like PCWAY, it's easy to design custom projects and LET THE NIGHTMARE of PCB to others

All the necessary files, are in my github repository, but if You have any reasonable inquiry, I will be glad to clear it fast. Best regards.

God bless You
