| Hi, Its really easy to do this project if youre not TOO lazy and have looked at the datasheet for the 'ls90. HINT - use a BCD decoder chip like the 74ls47. Both datasheets are easy to follow - its almost like cheating!! HINT #2, theres a very similar project (2 digit counter) already posted in this forum. :-P | |
