Hi.. i'm trying to built a fairly basic 7 segment counter based on the attached plan.
Problem i'm having is debounce (i think).. the button actives on release i believe, or atleast thats when the segment updates. but sometimes it's a smooth count up, other times it's a bit jumpy, which seams like debounce behaviour to me.
I've tried to add a 0.1uf (104) ceramic capactor both over the switch (from the one pin to the other (top right to bottom left of the 4 pins on the switch) to deal with it, OR going from the top right to just onto the ground rail, but all these seams to do is create a bigger and a bit more stable bounce. it now counts from 0 to 2, to 4, then sometimes to 8 other times round to 2 or 0.
I'm wondering if i just screwed up the capactor for dealing with the bounce or... I'm not quite sure.. any advice?
