Hi folks,
I'm new to the site as a user. I'm currently in the middle of a project for school where I'm building a 12 Hr digital alarm clock. I've got everything except the alarm figured out. This is all done using 7490 and 7492 ICs along with the 7447s and Seven Segment displays.
Where I'm hung up at is the alarm. My partner and I are trying to switch the display from showing the time to displaying the alarm time in order to set it. I was wondering if something along the lines of tri state buffers could be used for something like that. I'm not looking for the answers themselves, but maybe a direction to look in. Also looking for information on how to set an alarm. I'm guessing some sort of comparator setup? Or an IC that can do that is built for that purpose?
Any help is greatly appreciated!
