can you please give us your idea how to display
ALARM and CURRENT TIME, using or not using multiplexers..
using TTL..we are using 4 Seven Segment Displays for both hours and minutes
this should how it works: for ex, your current time is 12:00AM and we want to set the alarm at 12:30AM, by using for example a switch we can change the display to its ALARM mode, and then after switching it again, the 7SegDisplay should display the current time..
we appreciate your help..
