Hi,
I am going to build an alarm that will have 4 7-segment displays. 2 for the hours and 2 for the minutes. I will use 4 4510 ICs along with 4511 decoders. I have figured out how the counting up will work. I will reset the tens collumn of the minutes and hour once it reaches 6. However, I was wondering, how I could make 6 the maximum number when counting down.
