24 hour clock made using six 7-segment displays to make the format HH:MM:SS. The hex counters are made into base 3 base 6 and base 10 using an AND gate on the two binary values that make up the base number (1+2=3, 2+4=6 and 2+8=10) which causes a reset and a increment on next counter. The seconds unit is incremented by a logic train in bottom right corner. Please feel free to ask any questions.
