Hi all,
I want to make a clock, and I think I have the basics figured out, but I need a bit of help...
You may know that when a counter (mine is the 4520) it counts 0 to 9... Its the zero I need help with. Obviously, a 12 hour clock does not go>
12:59 >> 00:00 >> 00:01 etc...
I need it to, instead, go:
12:59 >> 01:00 etc...
Thats where I'm stuck... I don't know how to get rid of that zero. Furthurmore, I need it to come back again when counting like:
09:59 >> 1
0:00 (note the zero is back)
How, on earth do I do this???
I know how to switch the zero in and out when needed, but how would I get rid of it?
All help is most appriciated, the datasheet for the 4520 can be found
here and a useful site is
