Unless it's an alarm clock, why do you want an AM/PM indication?

It's a requirement of the homework.

@star72: Please don't hijack someone else's thread. Now you have your own.

 

Our professor told us to build a 12 hour clock with 2 LEDs for AM/PM indication. We will actually connect some pins on circuit to the corresponding GPIO pins on Altera DE1 Board (Quartus - Cyclone II Device) and program the logic gates used to make it run as how it should be.

Ours is AM LED on, PM LED off.
