Hi,
I need to make a 0-99 event bar-graph counter. I have tried to use two cascaded 4017 decade counters but I can't get them to behave properly. The first one counts 0-9 then it has a carry-out to the second to count ten, twenty, thirty, etc. The problem I keep getting is the second counter always has the tens LED on when I power up, then when the count on the first reaches 10, it increments the second counter to twenty. How can I inhibit the second counter until the tenth count? Any thoughts? Thanks.
